My rear window defrost doesnt seem to be working in my 95 grand cherokee ltd .. when i push the defrost button the light doesnt come on and the window doesnt defrost .. i hear clicking in the passenger side dash when i push the button and i have checked the fuses there also and all seem fine...any ideas?

Use an ohm meter to check for continuity between the two solder points on the glass (unlug the connections before checking)
I would suspect that if the grid has a break in it, then the light will not come on.

Could it have anything to do with the side mirror being broken? it is a heated mirror and im assuming that the defrost button controls that also ..

Does one mirror defrost? Check/clean the connection on the rear window too. That coils of black wire where the power goes to the window Defroster.There is a light just above the button which should come on when pushed.

Yeah the light doesnt come on at all .. and no the other mirror does not defrost ... i will try and clean the connections on the rear though... like i said i can hear something clicking over by the fuse panel on the passenger side so that tells me its trying to come on at least

If it was a dead realy would i still here the clicking from the relay when i press the defrost button? relays fail in 2 different manners. 1. coil failure = no click 2 contact failure= click but no current flow either way tis still dead.
