Rear Defrost Stoped Working

6 posts in this topic

last time i know my defrost was working, was a few weeks ago when the first snow and ice that came through real heavy.

then all of a sudden it wasnt. used to, it would even make water go away, now it just doesn't do anything. and it just stopped working pretty much over nite.

i cant find my manual anywhere right now. so could someone please tell me which fuse i would need to look at it.

or even better, if there is a more likely problem that has caused it to stop working.

In the fuse box under the steering wheel, Fuse/Relay location #7 is the 'Rear Defrost Grid Feed' fuse.

What exactly does "stopped working" mean? Does the light associated with the switch turn on with the switch and the grid not heat up, or doesnt the light go on when the switch is turned on?

The light comes on. And it turns off after a few minutes. So everything seems normal. But no heat.

I'm gonna go out and try the fuse tonite. Not that its gonna do anygood, its supposed to be fairly warm for the next week or so. So... not sure how I'm going to test it.

Get a test light and see if power is getting to the plugs at the rear window. If there is power, then the problem could be on of the contacts that the plug(s) plug into, or the heater element on the window might have developed a bad spot. Permatex makes a repair kit....cost about $10-12...for the heating elements.

^^^^^^ Thats what I was thinking. I have seen many more problems with the grid or contacts than with the switch / fuse in the rear defrost system. Sometimes it is as simple as one of the plugs go knocked off the contact at the grid.
