I always get a film on the inside of my windshield and windows, even after getting the windshield replaced. No one has smoked in the car since I’ve owned it and gotten a new windshield. I thought it may be the cabin air filter, but can’t seem to figure out if the 94s even have a cabin air filter? I know the 99s dont.
Anna Bruning the 1992-1996 do not have one either. Make sure you do not have a small coolant leak etc. on the inside of the heater coil. Most readiator shops can do a pressure test to see if you have a leak. If not then the only other way would be to totally disassemble your ducts etc. and clean those.
