well guys my AC was working just fine this whole summer until today when i put it in setting 1, 2 or 3, it doesnt blow air at all but i can hear the AC system going, BUT when i put it in setting 4 it blows cold air. doesnt blow anything in settings 1,2, or 3 though... weird i DID hack my intake yesterday but it was working fine yesterday too and im pretty sure that doesnt have anything to do with it does it?

thanks for your help guys

 

Sounds to me like you should check out the control unit in the dash.

Maybe the switch is bad. I am not sure how you would test it though.

Sounds like you need to read the FAQ sticky to me. The answer is in there.

 

HINT: check/replace your fan resistor (cheap $$ and easy fix yourself) located on passenger side of blower

 

i found it in the FAQ's sorry i guess i missed it while looking through, admins can close this thread if they want..
