so as the title says, the rear window defogger is out. i've replaced all visible fuses but it still isnt working. is there an inline fuse somewhere thats not easily visible? something else i should check out? thanx

 

I also would like to know.mines been out for a month

 

check the little cord things on the sides of the window and make sure they didnt come unplugged

 

this is going to sound stupid...but are they a bitch to plug back in? i got big ass hands and fingers.

 

i dont know i never had them unplugged. there is little covers over them, just pop off the cover and make sure its okay. theres one on the left and one on the right

 

just checked em. the one on the driver side was slid down A LITTLE bit. im wondering if it might have been enough for them not to get contact. well we'll see tonight i guess. its been freezing ass cold the past couple nights.

 

I repair these things on a daily basis. There is on most cars a relay as well for the rear defogger. Usually located in the engne compartment fuse box. Check you manual out and see if we have them in our cars.
As well use a pen style voltage tester and put the clamp end on some bare metal and touch the pen tip to each grid on the rear window. If its lighting up you have a bad ground which is located on the drivers side(the tab where the wire plugs in is the ground) could be the pass..I forget lol. then unplug the positive side of the defroster(other tab on window) and put the tip of the pen in that and the clamp end on metal...if it lights up you have power...if not then you don't.
I'd check the relay first as its the usual culprit.

 

i checked the relay....what a goofy prong system they use. my fuse checker lit up, indicating that it was working. just out of curiousity i called my local dealership. THATS A ****** $40 FUSE!!! WTF?!?!?!

 

Ya I know. GM isn't cheap for relays..you can pick up a generic one at any auto parts place for cheaper.

 

thats what i did. i went to autozone and got one for $8.99.

 

lol there ya go. I knwo impalas have the same rear defrost issues and I have yet to figure it out. Most people don't want to be charged by the hour to find a rear defrost issue at my shop lol

 

Heh. Mine sort of works. One of the sets of contacts fell off the rear window last winter.
