What is going on with my car ('86 300e)? When I get in and turn on the circulation system, there's an overwelming smell that fills the car. It's a super strong amonia smell that I swear smells just like cat pee. Now, there is NO WAY that a cat has gotten into my car and pee'd in there. I guess it's not impossible, but it's highly unlikely. Is there some air-filter that is desecrating? I mean the car is 16 years old for crying out loud. Did in fact, a cat or dog perhaps pee on the front of the car somewhere near an intake? Am I crazy? Ever heard of anything like this before? Should I just take the car on a long drive and run the circulation system on High with the windows down to flush it out? I did just start using the AC for the season? Is there any connection?
Thanks Guys and Gals
