maybe the switch is broken or the fuse/relay has gone??
The only window that is heated in any car is the rear window. As far as I know ther's no such thing as a power heated window
It's very possible as the heated mirrors and the rear defogger are tied together.
Blown fuse or a break in the wiring. There are kits to repair that type break.
i believe it is in the heated rear window
window heater not working
If your van is equipped with heated mirrors, the same switch that turns on the rear window defroster turns them on.If your van is equipped with heated mirrors, the same switch that turns on the rear window defroster turns them on.
Bulbs blown, or corroded sockets.
if the switch lights up then check to see if the metal connectors and strips on the rear window are ok if they are then i would say the rear screen relay is broken.
The heated, outside rear-view mirrors will warm up when the rear window defroster is turned on. That provides for effective snow & ice melting from the mirrors.
Dead short to ground in circuit When you turn heated rear window on - circuit is backfeeding and finding ground at shorted circuit
Then you only have one working window out of four.
It was not a new Malibu, but new to us, the rear defrost over heated (in the summer) and blew my window into a million tiny pieces.
