I just recently put in a new motor and fixed my dash pad by repairing and recovering it as others have done. Now I have an oily haze that keeps building on the inside of the windshield. I was thinking it might be the heater core or something releasing from the spray adhesive or vinyl when I recovered my dash. Anybody else have this after doing the dash pad fix? It keeps coming back within a day or two of cleaning it. Is it the heater core or the chemicals from doing the dash?

i is it possible that your heater core has a small leak when my core started to leak it would almost vaporize the coolent and it ended up leaving a film on the windshield feel the carpet on the pass side to see if its wet or you might have gotten somthing in/on the cowel when you did the motor swap and it was sucked in the system and sprayed on the windshield i have had a couple of cars that i bought where the po smoked in the car and there was a film of smoke on the windows that would look clean right after i was done but would return shortly after i had to use a degreaser like simple green wich took the film off for good

I have been checking the floor for water and nothing. I would hate to replace heater core when I didn't have to but I just may have to. Anybody else fix and cover there dash and have the heat draw out any chemicals?

Chemicals on the dash can make the windshield look hazy. They can get that way from heat or just over time.
