I don't know what's going on, but everytime when I turn on the a/c (after the car is parked and off for a period of time, at least one or two hrs), there's this really funny and horrible smell. It smells "sour" or something, but it goes away after like a few seconds after the a/c is running. Any idea what it is and what can be done? Thx

 

search...this was asked about two or three days ago.

 

i searched all the way to like a week or so and still can't find it. or maybe i overlook the topics.
