There is an awful smell in the car. It is not cat urine. After removing the passenger door panel the other day I realized the smell appears to be coming through the vacuum vent on the passenger door. Is there a possibility of a bacteria build up within the vacuum system? Any suggestions on how to get the smell out? Thanks for yopur help!

psherman- type in mold or ac/mold in the search engine. There are a few things there that might help.

Thanks for the advice. I will give it a try and hopefully I can get to the root of the problem. Did you by chance have an odour problem in your MB?
