rear window defroster problem My rear window defroster sucks. I get in my car and start it, push the rear defrost button and the button lights up, but only stays on for a lil bit. It barely starts to work and then shuts off. and it won't go back on for a couple of minutes.
any suggestions?

Mine does the same thing. I want to know whats up with it too. Does yours sound like it clicks when you push the button after it cuts off? Mine does but it still doesnt work

try this: unplug the connectors at the rear window. the two terminals attached to the glass , check for continuity with an ohmmeter , if you have infinite resistance, you have a broken grid (the little lines in the glass ),also visually inspect the lines in the glass for broken lines . might even be metallized window tint causing the problem . GM does have those on a timer that shuts it off after a little while , might end up having to live with it.

The breaker (the silver guy in the fuse box) that GM used were of very cheap quality. Remove it and replace it with a better one or just put a fuse of the same amperage in its spot. I did this two years ago and its worked ever since. The timer will still work also.
