Rear Defrost Not Working HELP - 12/16/2006 2:25:28 AM

I have a Cavi its a 2004 Standrad 2.2L Regular (I say regular because it has no extra badging on the back and has no ac)

I just had my windows tinted and the rear deforst was working fine before now they dont. I had checked the fuse it was fine and the defrost lines that go across the window they are all fine, the rear defrost light comes on normal as it did before and then auto matically shuts off after 10 mins then 3 mins there on after that (I think thats how it goes) I checked the rear defrost clips and saw no damage I removed and reinsterted them and it worked great one time after awhile then stopped and havent been able to get it to run again(melt ice or defog). Maybe there is some dielectric grease im supposed to put on the clips or something? Called the tint guy and he said that was not normal for the defrost to fail, I will go to him if I am totally unable to find help here! Please help!!!!

Also with the multimeter on the OHMS setting ... disconnect the wiring to the " clips " and check for continuity through the filaments.

I suspect there is an intermittent break in the filaments or where they end at the " clips. The filaments are very fragile.

actually the filaments are wired in parallel so if one breaks the rest will work

How is it differant in operation since you had the windows tinted? It sounds like it is working properly to me?

I just re-read your post, the operation of the light sounds normal but I assume you have no de-fogging taking place. Verify that you have voltage across the grid and that your ground is good.

I apoli.if I was unclear, the operation is not different with the tint but its the only factor that was induced to to possibly cause the defrost to stop from melting ice. What I am saying everything seems normal, I have checked all other factors its just the connection of the clips I would assume is causing the defrost to mal-perform.
