I just purchased a 2001 Chevy Impala from a local dealer in impeccable condition- 95,000 miles, 3.4 V6. When I turn on the A/C there is a moldy musty smell. There was no cabin air filterWe put in a new cabin air filter but that has not helped. The car sat on the lot from November till June. How can I make it smell better?
