My A/C stopped working from one day to the next. When i turn the **** to turn the air on only my defroster works. I have turned the ***** back and forth but only the defroster will work. Know why this is happening? Please help.....summer is coming...

 

Welcome to the Tahoe forum. The defrost is the default position on most HVAC systems. Possibly a vacuum hose is detached or broken or the selector valve or actuator is leaking.

 

Thanks. This will be very helpful. I think the selector **** is what broke. Im going to buy a new unit and see if that fixes my problem. Thanks.

 

Let us know how it works out.

 

Worked like a charm. I have A/C running full blast now! Must be something with the climate control unit
