well im horrible with ac.. maybe because ive never ever messed with them.

truck is in sig has digital daul ac control. when i turn the ac on you can hear the compressor kick on. but no matter how high you turn it up nothing comes out of the vents. just a faint feel of cold air. you cant even hear air blowing. im gonna guess the fan or fan speed switch but i dont know.

you guys have any ideas?

 

blower motor resistor? (I think thats what it is called) Its underneath the passenger side and simple to replace from what I remember reading. Im going to look for the thread that I was reading earlier.......Ill edit this post and add when I find it.

EDIT:

Here is one with a video.....

Here is another one.....

Let us know if that fixes it

 

Thanks bro. I have no fan at all though. Can't even hear it. Hope this fixes it

 

It very well might. I know it's a common problem on some other GM cars.

 

With automatic a/c you will probably have a control module in place of the blower resistor. I'd start by ruling out the easy stuff so check for a blown blower fuse. If the fuse is good you can run 12v directly to the blower motor and verify its funtional. After those your down to the a/c control head or the control module(fancy resistor). PM me your VIN if you need part numbers.

 

wrong section chris. smhhh

 

How is it Stephen? Lol. O well they can move it I hope

So it's possible it's my actual Ac control in the dash? It works like I turn everything on. Just nothing will blow out unless I'm doing like 40 mph u can feel cold air slowly coming out the vents.

I'll check blower fuse and report back

 

Im almost sure this is it. I have the same problem no air.. talked to my cuz who's a mechanic said it was the blower resistor or something like that on the passenger side.. I just haven't time to fix it. Don't sweat it im sure that's what it is.. if u do happen to fix it post up the part number lol.. I've been to busy to take a look.. plus summer is just about to start ..
Lol..

 

15-8087 I think it is. Lol. Scroll up and look. But that's for digital one

 

15-81087 that's it
