Air Conditioner will not turn off even with the truck off it still blows

SOURCE: no air, ac, heat out of in dash face vent

I changed my switch..on my dash...that controls the different settings. All settings work fine now.

Your blower moter is under your glovebox and very easy to replace.I dont think thats your ploblem.I would pull off the dash.It will snap right off without breaking anything.Then pull out the part that holds the selector switch for the fan speed.Then you unplug that switch.Clean the copper contacts.Plug it back in.If everything works again like it should and did in my truck then it is either that switch that is bad or the wiring harness.I would replace that switch.

SOURCE: Dash vents will not blow air. Defroster and floor vents blow fine.

Is it a new vehicle? I had a new vehicle that had the same problem. Answer was that the holes weren't punched out of the vent.

Same car, same problem. Press MODE, FRONT and REAR buttons together to reset tempreture. You probably need to replace the sensor GM part number 15047946 it is in the front grill email me for a picture. [email protected]
