pearlwhite97ES Posted July 11, 2008 Share Posted July 11, 2008 I recently bought a 92 ES with 74k miles. first problem is the windshield fogs up when I put the A/C on..I was wondering what this could be? It appears to leave residue behind also. Anyone know what might cause this? thanks Quote Link to comment Share on other sites More sharing options...

OR a leak in your heater coil. Is the floor on either side of the console damp? Is there a 'sweet' odor (other than air freshener, if used)? A leaky heater coil will leave a residue on the windshield. . . . that when you clean the glass, within a day or two, the residue returns. (And it's 'oily' too!)

I've checked for moisture on the floor board and have never felt any wet spots...the A/C takes a bit to get cold but once it does,it's really cold. Also it seems to do it more when i step on the gas more than a slow take off. Could it be a A/C regulator valve? Quote Link to comment Share on other sites More sharing options...
pearlwhite97ES Posted July 18, 2008 Author Share Posted July 18, 2008 Has anyone had any heater coil problems? I was just wondering what the symtoms could be...thanks Quote Link to comment Share on other sites More sharing options...
pearlwhite97ES Posted August 14, 2008 Author Share Posted August 14, 2008 I had the A/C sucked out and it had 1.74 in the system The A/C tech said It calls for 2.00 high and 1.8 low. Seems If I had a evaporator leak I would have alot less r12. I cleaned the windshield really well and noticed no oil or fogging for a week until I put on my defrost one rainy night. Could there still be some oil in the evaporator that could come through the vents when the heat is on? Also,would the heater core only leak with the heat on? This problem has me baffled and I don't have enough money just to drop it off at a shop. Any ideas or help is much appreciated. Quote Link to comment Share on other sites More sharing options...
