Best Answer

The rear window defog relay is what keeps fog from building up on the rear window. It works by using current to warm the window to prevent moisture buildup that can hinder visibility.

2001 Yukon Heated mirrors don't work when rear defrost is on?

Only thing I can come up with is the wires going up into the fuse block where the rear defrost relay (RR DEFOG label in the manual) are switched so when the relay is activated, which normally turns on both mirror heaters and the rear defog, is turning off the mirrors and turning on the rear defog. You need to unbolt the fuse block mount so you can lift it up and pull the RR Defog relay wires out the bottom and reverse the two circuit wires but not the two supply wires. Wish I could say right now what colors they are, but I don't have that. Odd situation...

Is there an inline fuse to the rear defroster in a 1991 Pontiac Firebird?

I'm sure there is a fuse somewhere, but the electrical connections for the rear defog are made thru the struts that hold the rear hatch open. this is why if you buy new struts for that car they will ask you does it have rear defog. the struts you need must have an electrical connecter at the forward end with a wire attached to each strut. go look.
