When I turn on my A/C a strange smell comes out, as if there is mold inside where the water should drain. Any suggestions would be greatly appreciated.

 

GM has something you can spray in your HVAC system to cure that problem, I believe.

 

The AC system itself is under pressure and sealed. Sounds like your AC condensate line might be clogged if it's not dripping - get the same smell with just the fan on? I'd also take a look inside the blower box.

 

yea, it does happen with just the fan, but not as bad.

 

Tried to edit my post twice - no worky. See if your carpet is wet on the passenger side.

 

no the carpet is never wet
