I have no dash😢

After replacing a variety of ac components, I took my truck to an auto mechanic and he couldn't find the reason for the ac clutch not engaging. Been driving it for quite some time with the inside windows fogging over, not fun. So today, saw your video, replaced the short oem vac lines at the junction you pointed out (they were dry rotted) and was able to get ac clutch engagement and full heat with air movement from the defrost vents to the floor vents! Thanks so much for the tip!

Was having the same problem with just air coming out the defrosters . Figured I'd be having to tear the dash apart to find the problem, but then I watched your video and found that when I changed the fuel filter I must have knocked the line off . Thank you for posting this and saving me the aggravation !!

After searching video after video and dreading removing the Blend Door motor (huge job) I found your video and within 20 minutes the problem was solved finding a small 1/8" vacuum line under the hood broken. Patched it with a temporary rubber sleeve. Very thankful for your post!!!

You have a new subscriber!! I had no idea where to start, KZread rocks when it comes to things like this. This definitely save a $175 diagnostic fee I'm sure would have been charged by almost any shop. Mine had become disconnected and had not been working for some time. Hope it fixes my cruise control too.

Glad it helped, such an easy fix that most shops would love to get easy money on.

The vacume line for the heater controls on this 99 dakota had been cut inside the engine compartment...i used a couple inches of rubber tubing to splice the line back together....the heat controls work now and there's heat now too...thanks brother..👍

Awesome! Thanks, glad I picked to watch your video first. 30 second fix, line came apart, didn't realize.

Thanks, man...! Fixed my 2001 after checking line.

The vacuum was exactly my problem. Not only old dry rotted leaking hoses but further along that hard plastic tubing manifold along the firewall it had separated and needed splicing together with some small diameter vacuum hose. Replacing the dry rot and rejoining of the manifold allowed vacuum build-up and regaining control of a/c output vents!

Man this helped me so much thank you so much I found a hose that was disconnected and we reconnected it and every function works now

With hindsight I should have checked vacuum lines first; however after fixing the same issue on my son's 2004 RAM with the HeaterTreater kit I bought the blend door kit for my 2001. After installing the HeaterTreater blend door connector I realized my mistake. Found this video and then immediately found a cracked vacuum line in the engine compartment about 3" from where the line entered the firewall near the AC lines. I was able to make the repair by sliding new vacuum hose over this small vacuum line.

I’ve never been more pissed but happy at the same time I didn’t even fix them yet I touched them and it fixed my problem now I gotta change them out

This worked for me! thanks!

Excellent! Worked for me. Thanks!

I have the same issues, but also controls cruise control as well . This video was well explained thanks

You ever figure out the Cruise control I’m having that and this problem right now

On the second gen rams the hvac unit has doors that use a vacuum motor to position the door; the vacuum motor responsible for air coming out of the defroster vents all the time is the one mounted on the far left of the unit there are just 2 ways for it to fail, loss of vacuum or mechanically when a small plastic pin breaks off which is what happened in my case. The fix was easy, I drilled a hole in the door arm and put in a bolt and nut, it's fixed forever; at the far right side of the unit is the door for fresh air or recirc air. When the A/C is in max A/C mode the air is being recirced. As for temp control, it will control the blend door either with a mechanical cable or a stepping motor. Hope somebody finds this info helpful

That's crazy, I would have never thought of vacuum lines for something electrical, thank you for the post, I will check that out. I had already replaced the temperature control panel new about a year ago so I don't think it's out that soon and I also put in a new fan motor too at that same time so I know it can't be those things

Thank you

My truck is a 2000 dodge ram Laramie slt quad cab long bed 1500 it has ac works good, and the heater works good and strong as well but through the vents in the cluster bezel and the passenger side dash pad vents, but when I put it on defrost it doesn't work heat still comes out of dash bezel vents and the passenger side dash pad vents..

Can somebody help me please???? The line that’s running inside the cab what does it run to???

Thanks

no shit. My line was disconnected under the hood wow thank you

My problem is that my ac blows fine, but when I am accelerating my ac will switch itself to coming out the defrost vents, until I am not accelerating and then it goes back to the top vents. I asked people and no one I know has a clue what to check.....driving me insane!

You have a vacuum leak. Check your vacuum tank for a leak. The vacuum tank builds and saves vacuum for when you have minimal vacuum under acceleration.

thank you. You are jesus

Same on v8?

My 2005 Dakota defrost and floor vents worked but not the dash board, I beat the shit out of my dash, took apart a few vacuum lines and blew in them. Advanced auto employs morons so I came to you tube. It is now working and blowing out the vents ! My hand hurts so don’t punch your dash

Mine broke off right at the firewall. I either have to take the dash apart or drill a big hole in the firewall

I have a similar truck to yours but 1500 and the 5.2 litre 318 magnum v8
