AC question
 

So when the AC is on in my 09, a film forms on the windshield and a bit on the dash. It comes off with window cleaner but is pretty thick. Anyone else have this or know what it is and why it happens? Thanks.

I have seen this on cars where the owner and/or passenger is a smoker.

I don't smoke, doesn't smell at all like anyone has smoked. Thanks.

The only other thing that I can think of is possibly replacing your cabin air filter. You may want to give the inside of your windshield a good cleaning as well. The heat, coupled with the humidity in FL is notorious for fogging glass and leaving a dirty film. I was in the Palm Beaches last summer with my other vehicle and I know what you are experiencing. Good luck.

clean iur windows more often?

Happens to mine too. Especially at this time of year.
