Outstanding Tutorial!! This is the exact problem I'm having. I have to jiggle the harness to keep the blower working. Thank you!

Old video put it worked 👍 ac blower turnoff on me going down the road so I put it to get air from out but left the ac on so the air from outside can put into the cab cold and I check fuse it was good I started touching the cables that you touch and got slap my air. Thanks a lot man take care 👍

I was just missing the fuse I dont know why. But wow quick and easy fix. You saved me some time and money. Thank you.

Thankyou it was great help

Very excellent video thanks for posting. Viewers: please be advised that your replacement fan may have a different electrical fitting from the original fan that is on the truck. For this Freightliner sells on adapter pigtail.

Yup its called a jumper harness. And actually the mount screws don't even line up

Your blower is get power from somewhere Check the sam cab module behind the glove box. Freightliner had problems with water corrosion at the plugs .

Súper recomendable nice video 😜

Yup. Always think about making money and not just helping people. ME ME ME ME ME....

😊 thank you so much you saved me my truck has the same problem

Check the ground wire it’s as important as the power .There is probably no ground with the ignition on.

So was it the fuse the connection or the actual blower motor

Sorry not sure.

Very informative video. My blower stopped working suddenly. Trouble shooting now and I have power to hot side of plug even with control knob in the off position. Is that normal, seems odd to me? Thanks

Thanks for that info.

Big Rig Fix having problems with my bunk a/c...I go to fuse wiggle it and starts working but stops minutes after...the cab is working great just bunk no electric getting back thier after hitting fuse...Thanks bro

Yes I do have power on both blowers, but front AC (The cab) is ice cold, the sleeper air blower fan speed is good but it’s temperature is not cold (Warm)

Big thanks

I have the same issue on my Cascadia I being shaking the wire to get the fan to work

I have a cascadia that the motor works, but while blowing cold air it’s stops blowing and then blows back again by itself. I reset it on the controller and it works and later goes back to not blowing. Any advice that could help?

I like the good work that you sharing with other owner operators, on my 2012 Cascadia, my AC is cold in the cab but warm on the sleeper!!, should I change the blower or the main 3 switch control panel?, 🙏👍

Check if you have power at the blower.

Could be the rear thermal expansion valve. If it’s blowing (even warm) then the blower motor is good

Cool

2011 cascadia,I have my bunk a/c not coming on,when I wiggle the fuse it comes on,but goes back of in minutes

How do you change the harness

Damn man just bought a new fan and jumper harness but this was all I had to do. They don't even make those OEM blower motors anymore and the new one the bolt screw mounts don't line up to the old ones. What a fucking mess this has been. Also could not get the damn plug off so I know it was melted inside

Thanks

Thanks for this video man, it seems that plug failure is a common issue. You SAVED ME!

My Cascadia bunk ac fan stays on even after the truck is off. When truck is on I try to turn it of and no action. The fan stays on

Nice , excellent job 👍

What’s that tool your using to check the voltage? Looks different than my meter.

2011 cascadia my blower stays on even when the truck is off

Hello I have a freightliner Cascadia has no cold air in front but has cold air in rear , I did replaced EXPANSIVE VALVE on the front side, recharge the freon , but it did not change anything , front still has no cold air, and rear has really cold air . Do you think the new EXPANSIVE VALVE is not working or maybe something else cause front AC NOT cooling at all？If you have time please let me know I appreciate ， thank you

Hi friend. Good observation. I was able to remove that Torx screw by forcing the Torx socket on to the screw head and pushing the plastic - molding slightly to the left while unscrewing the Torx screw. The good news here is that plastic, like steel has some flexibility so you can get away with this without breaking anything. Getting that screw back in as a little bit more tricky. I set it into place and then use needle-nose pliers to rotate the screw as far as it would go and then use the Torx socket same as above to finish tightening it

Great video. My blower stays on all the time even when i turn the truck off. Any idea what it could be?
