Does anyone else have an obnoxious smelling film being blown (from the ventilation system) onto the inside of their windshield? The film looks a bit like a white powder and it is slighty oily. It is not easily removed from the windshield. Could this be residue/libricant from the A/C refrigerant? Can anyone provide any info to help correct this problem? P.S. The cooling system has not lost any antifreeze and a pressure test showed no antifreeze leaks, so I have ruled out leaks in the heater core.

 

A/C refrigerant shouldn't be able to blow into your car through the ventilation openings.

There is a somewhat waxy/oily film that gets on the windshield when it is hot. I assumed that this was the volatile hydrpcarbons and such leaching out of the interior plastic.

 

This is probably the outgassing of the interior plastics. I am in AZ and the problem is not very noticable. You can mix a bit of white vinegar and water (about 10% vinegar) put it on a cloth and wipe a couple times. Then, wipe with water on a cloth, then use a good glass cleaner and soft cotton towels, and it should look like new.

 

also, make sure not to use things like amorall on your dash(doesn't matter if it's regular or low gloss).

 

i too occassionally get this white residue when the car sits on hot days. i just use a heavy dose of windex all over the winshield, then i use the windex wipes over that & it cleans it up pretty nicely. its happenned twice so far since its been gettin really hot here in florida & i believe its starting to do it again. i remember this happening in a few previous cars ive had & it turned out being the scotchguard on the apholstry. in time it stopped fogging up...im hoping for the same with the z...........
