well in my neck of the woods its starting to get up there in the temp range. so i clicked my ac over to 5 and it doesn't do anything. 4 works just fine. any ideas?
i thought i heard of a diode that burns out or something easy like that. but now i cant find it. so any help would be appreciated. thanks!

 

right above the passenger flooboard there is a big plastic peice, take that off and behind it is the blower motor and evaporator core. right in front of the blower motor in the air track is the blower resistor, its probably burnt out.

 

yeah my resistor went out last summer....super easy fix

 

I have this same problem. A few months ago, I found a website that walked you through the process to fix this. Now, I can't find the stupid thing. Any of you guys mind sharing details on how to fix this? Expensive to fix? I rarely, if ever, would use it...I just don't like anything to be broken.

 

 

Care to elaborate?

 

maybe you should pm the information, since they just got lost in a "7 post" thread

 

While you guys were busy wasting our time, I found the answer.

I bought my replacement harness at The Electric Connection. The part number I used on their website was 15-81086, and it was high quality and fixed my problem completely.

The installation was easy, and the instructions from my prior post were spot on.

I believe part number 15-81086 is for the trucks with manual A/C controls, and part number 15-81087 is for the trucks with automatic A/C controls.

 

Omfg!
