sprayed some cleaner into the vents at the bottom of the windshield area. worked for about 2 years. now i have to find the cleaner again. i think i got it from o'reilly's.
I purchased the car with 110,000 miles on it. There was already a problem with the odor when the heater was running or when the air conditioner was on. Moderate smell similiar to dirty kitty litter. For years I ran the heater at 80 degrees and turned the heater off when the car became too warm. The heat seemed to keep the bacteria under control and the smell was barely noticeable. I don't use the air conditioner very often. A mechanic used some liquid that stopped the odor for about 2 years. Another mechanic used a powder -- bad odor was reduced for over a year but there was a powder smell. I returned to running the heater at 80 degrees. I've had the car for 12 years. Finally, this past year (2011-2012) the odor problem seems to be gone.
I bought the care used in 2007. It had a musty odor when the A/C was turned on. Dealer said it was only because it hadn't been used regularly. Now 2011 still has musty odor when A/C turned on but engine is dying so the car is parked. Like to thank Dodge/Chrysler for a wonderful engine design. Dennis Snyder
