I think that is the problem with my '89 Cougar's power window, driver side. As always, I try to see on KZread any repair tips before tackling any job. So glad I found this. Excellent hack. Thanks.

I just wanted to leave a quick note to say thank you. This video saved me close to $200 in parts for my Ford f150 windows. With the information in your video, I was able to repair my original window motors, instead of having to replace both the motors and the regulator (since I could not buy just the motor in my area). Thank you! 😊

Excellent, Jennies Garage. From your idea, I 3D printed some spacers like the nut. Thanks, 100%!

I Was Trying To Find A Video On A 2007 Jeep Liberty Drivers Door Window Motor Video And Came Across Your Video. I Never Did Find A Video Like This For My Sons Jeep Liberty. I Saw That I Had Commented On This Video 9 Years Ago, WOW! Time Sure Flies By.

Yes it does. It was a younger me who made this video!

There is a lot of speculation about how and what this mechanism is for and how it goes about doing it's job. After a detailed examination of the mechanical window operator from a 1994 Ford Explorer the following is my opinion of the design intentions of the maker. The electronics associated with the window operation system is basically a current threshold sensor. When the current supplied to the motor exceeds a predetermined design level, the electronic controller turns off the power to the motor. The panel switch resets the sensor when the window is requested to move and the process starts over. The three barrel shaped parts, that many in these comments are replacing with nut or whatever, I still believer to have been produces from a carefully calibrated formulation of urethane. The comment in the video concerning the destruction of the "balls" at the 4:14>> point in the video is totally incorrect. The metal gear with three cam shaped bumps on the underside is seated in recesses in the nylon gear and limited in it's rotation with respect to the nylon gear. With the "balls" (I shall call the barrels hence forth) out of the mechanism the nylon gear cannot fully rotate without carrying the metal gear with it once the space allowed in the design has been traverse. Therefore it does not offer any resistance overload protection. That would be a poor design in any event by depending on a component that ages and the properties over time are, to some extent, unpredictable. However, the design is cleaver and in spite of the of the barrel material properties instabilities, a fail-safe system has been created. The barrels are a deceleration cushion and timing system. When the motor is moving the window the design of the current sensor permits the motor a specified range of current for that function. If the window tracks get dirty and stiff the current required to move the window MAY exceed the threshold of the sensor and shut down the motor at any point. The current sensor is part of the safety device. The elastomer barrels in the gear assembly provide a stop cushion at the end of travel and give a short period of time for the electronics to respond before the cams run out of room. When the window hits the end of travel, the nylon gear keeps turning and squeezing the barrel shaped elastomer parts which puts extra demand on the motor to the point of tripping the electronic current sensor before the cams on the underside of the metal gear come to the end of the available travel built into the nylon gear recess in which the metal gear resides. In order to simplify the problem of what value to set the current sensor at and eliminate a number of variables that the current sensor has to deal with, a large balance spring is in place to adjust the current, under normal conditions, for window going up to be the same as the current for window going down. Replacing the elastomer barrels shaped cushions with anything that does not compress at the correct rate totally defeats the design purpose of the system and will damage the system and may compromise the safety of the system, for at this point, unforeseen reasons.

I've been fixing those safety plugs for years on my 1973 LTD and my 1990 Crown Vic. I've been making my own using a 7/16ths in plug cutter, (for wood) cutting plugs from a sheet of 1/2in thick Poly type of plastic I got from Mac's hardware. Those plugs just break up over time, even in the windows that aren't used much. On my 1990 there is a small c-clip that you must take off to get the metal gear off the shaft, great video. Anyone feel free to ask me any questions, I'll be glad to share anything I know.

Thanks for posting this. I replaced both gears in the back windows of my '89 Town Car. I had bought all new parts for $15.99, made it easy to just pull everything out of the motor, clean it out and replace.

Thanks, this will work for my 1991 ford 250. Like the last part too, showing were to drill to get to the motor bolts. This only the second video that did not require drilling out the rivets and taking out the entire assembly. Much easier. Thanks again!!!

The protection of the plastic ball pieces is so you dont break the glass if the stopper switch malfunctions and the window continues to go up, they should strip out before the window glass breaks

Hey man your video helped me out a lot I love it! I watched your whole video on how to fix the window motors and what you did on yours I did to my window motors too and it actually works great 👍😎

thank you for this video, it saved me 70 bucks, doorman sells a wheel and the 3 little plastic cylinders for like 12 bucks now, but that old grease is what caused the problem since plastic is a petroleum product it broke down and probably is what caused the slow hard friction on the window motor.

very helpful, I have a 1987 Bronco 2 wich has the same system and it had the same problem.

Excelente video. Me ayudo mucho para mi Ford. Saludos desde México.

Just went out to fix mine, and somebody evidently had seen your video before. There were nuts inside of it but they were too small so they just were shoved to the side and didn't work. I replaced them and now it works beautifully. Hahaha

Great job man. I fixed one with my father before I saw this video. We cut down a bolt and used it in the same fashion that you did with the nuts. But the nuts look much easier because he don’t have to cut anything.

💯 percent great video, thorough and well spoken. Ty buddy I just fixed my window trouble on my 1992 ford bronco👍🏼💪🏽🙌🏼

Ford has been using this same window lift mechanism for at leat 25 years, and this fix works great--and cheap. Instead of metal nuts I use a peice of nylon dowel of the appropriate size, then I cut three pieces to length (1/2" or so) with a hacksaw and put them in with grease and they work as good as new.

thanks for the video jennie. the drum shaped nylon inserts are available on amazon for about $9. i ordered them today and will report back on the install and operation. since these suckers are in a 1997 lincoln it makes sense that they would be at the end of their service life. this is my new first response to failed window actuators. i had a similar condition on my washer machine...the little nylon pawls that cause the agitator to go one way only were toast and i replaced them for about $5. good old youtube!

Nice video, let me say the following. The original plastic nut failure is designed to protect the plastic gear, thats why it fails in a reasonable period of time. If you install iron nuts, for sure, in the near future the plastic gear will be broken or the glass could be stucked in a closed or open position. I am suggesting to elaborate this 3 plastic nuts using a piece of nylamide. Better results.

+Juan Antonio Ayala Piña Good ideas, I agree that the plastic pieces are the intentional weakest link.

Guys, don't use this method. I just opened my motor and someone had put nuts inside. The white plastic gear is now cracked. Dorman makes the replacement plastic plugs. These plugs are a safety feature - they break if something (like someone's head or arm) gets caught in the window.

Used to cut 45 ACP cases cut to length.

The edges of those nuts are going to wear the big plastic gear out. Bad choice to use nuts instead of something with smooth sides. Just saying for future viewers.

Thank You! You're super smart! ;)

Just performed this repair...the nylon cylinders were available at O'Reilly's auto parts in a plastic clamshell hanging in with the emergency repair parts. They were $8.99 for 3 and needed to be modified by sanding one side of each cylinder flat until they fit.

There is also considerable debris, from the plastic plugs inside around the worm gear and up the shaft.

Well I’ll be giving this a try tomorrow

a piece of dowel rod with fuel line around it works the best, cut it to i think 3/8". it's been awhile! (sorry) a little better than using metal bolts that can eat the plastic, as the rubber on the fuel line has some give!

Hi, thanks for the vid, I get the idea that most cars, especially Ford models uses this type of set ups. I just wanna make sure before I attempt, I know what I'm dealing with. My car is Ford Focus Ghia 1999. When I press the button, I hear the rolling sound, but the window doesn't move, is my problem similar to yours? thanks

Not ever having disassembled a new window drive, I can't say with 100% certainty how, and of what materials makes up it's construction, however, being a machinist and over 45 years I have designed and built a lot of machinery for industry, I can comment with some degree of authority on the design of this device. Safety first. It is, in my experience, it in not common to design a self destruct safety device unless there is absolutely no other way to go. Self destruct designs are usually reserved for s large system where life or death situation would be set up in the event of a device failure. Such as an elevator cable breakage where there is no concern whatsoever about saving any portion of the system vs compromising the effectiveness of the safety action taken during the event. After examining the shapes of the components and realizing what the demands of the application are, and applying my several decades of experience, I am offering the following statement After examining the shapes of the components and realizing what the demands of the application are, and applying my several decades of experience, I can make the following statements based on my observation of your presentation. Yes, a child's neck in a closing window could definitely be a life or death situation. However, determining the forces involved and calculating the breakage point of a particular plastic in the configuration that is demonstrated in this design would pose many obstacles to jump over during the development of the device. One would need to establish a relatively precise stress point and select a material that will fracture at exactly the right time and under specific conditions. This type of material would have to resemble glass which would not be suitable for the rigors of the application. This would very difficult to get it to work and not be reliable. I think the design needs more latitude. I suggest that the designers took another route. If the thing that goes in the space is hard, what is the point of all the details in the design?? There are simpler ways to make a breakaway self destructing drive. An elastomer (compressible material like rubber) has a broader window of tolerance to stress. The material can be tailored to exhibit specific compression rate properties similar the the compression rate of a coil spring like the ones on your engine valves, but in three dimensions instead of lineally. Speculating from the shape of the cams on the underside of the output gear I would suggest that the components that fill the gap between the cams and the triangular body in the driven gear are barrel shaped to distribute the driving force over a larger area than would be the case with spheres (or nuts) and are possibly fabricated of a carefully formulated urethane that can allow the cam to compress the urethane barrel at the needed torque value and slide on past to the next cavity continuously until the motor is stopped by whatever means that may occur. The lubrication allows the cam to slip over the surface of the elastomer without abrading the material. I would think that the lubrication would probably be silicone based for stability and longevity. By adjusting the shape of the barrel and the shore (stiffness of the material) of the elastomer it would be relatively simple to tune the system to required performance and be repeatable over thousands of units plus be inexpensive to produce. So where is the fault causing the material to breakdown? Possibly the lubrication was not thoroughly evaluated for compatibility with the specific formulation of the elastomer. I can't really think of any other explanation for the consistent failure of the system given the way in which it fails. The crumbly remains shown in your program suggests that the material is, or was, urethane because when urethane breaks down that is exactly the way it happens. Crumbs. This may be just smoke, but that is what my experience tells me.

Excellent analysis, I think you're correct.

overall this video was quite helpful. i do have one question. why did you take the time and effort to clean up the plastic gears inside the motor assembly and left the metal drive cog which actuates the window lift mechanism, clogged up with detritus ? it would seem that the metal cog would not mesh well with the window lift mechanism and would be yet another failure mode you would have to deal with on down the road.

Nice I did this to my 89 F250, but I dug thru my box of extra stuff and found some plastic sleeves (from and old TV repair guy that used to won my house b4 me...

Well done

Thought you'd like to know that I took apart my broken window motor (89 Bronco II). Not sure if this was stock or if a previous owner had done this, but the ball bearings were metal and it was the large plastic ring that cracked and caused the malfunction.

Ball bearings work great

Since I entered my original comment I have had the opportunity to examine one of these units up close in person and while some of my earlier remarks I believe to be valid, some are definitely in need of correction based on the new found knowledge from the close examination of the system. I will enter a new comment soon with additional insight. The new information is: That while the total window mechanism AND the associated electronics act in combination as a safety device, the mechanical unit in and of itself is not a safety device at all in any way. Its purpose is no to protect the glass or a body part in the opening. It is a very cleaver device. I will explain soon. Thanks.
