A/C Musty/Mildew Smell
Just wondering if anyone has a wierd smell when they start up the A/C? The best way to describe it is a musty or a mildew scent - not the nicest thing in the world. It does go away after about 2 minutes. Anyone know? Any quick fixes?

The only way I found to stop it is switch over to vent a few miles before I get to my stop and let things dry out..

It is possible that the drains are clogged, they are located in the lower corners of the windshield. They can be accessed by removing the wheel well panels and look up. They are roughly 6" long and made of black rubber. There are two per side.

GM dealers sell a product called Frigi-Clean or similar, you spray it into the HVAC air intake with the system running and it kills the mold on your evaporator/condensor. Worked GREAT in my car which had a strong mildew smell.
