Rear Window Defogger Not Functional
-Joel
If the seat doesn't work, I'd say start by replacing the fuse/circuit breaker and see if that solves the problem. It's a silver colored fuse in the panel that's on the side of the dash.
If you've done any electrical work recently, check that wiring and the area that wiring runs through. My rear defrost has been out since a tranny temp gauge was install. I've tried replacing the fuse..didn't help. Haven't had the time yet to check up in the dash but I suspect a wire got pinched or is loose when the wiring for the gauge was put in.

If I understand you correctly, yours never come on in the first place? Check to see if both the connectors are connected on the window. OHM out the breaker too.
