Where is the rear defroster fuse

2003 Chevy Cavalier ? Did you check fuse's ? HVAC fuse 10amp. & RR DEFOG fuse 30 amp . Both located in the instrument panel fuse box . Do you know where that is ? Open drivers door end of the instrument panel , plastic cover remove . Diagram on inside of cover

check fuse... check wiring to the switch... check wiring to the rear window...

RIGHT SIDE INSIDE THE TRUNK BEHIND THE COVER IS ANOTHER FUSE BOX!!CHECK THERE BUT FOR THE EXACT FUSE OF THE REAR WINDOW I NEED VIN TO CHECK!!!

Most GM cars and trucks use the fuse panel for safety with the rear defroster...Check your owners manual for the location of the fuse block...I think it is inside your glove box...Try the fuse first...if not the fuse...your options include replacing the glass inserted strips...(do not remove) with a rear shelf defroster blower motor... or an add on rear window defroster...Your auto parts stores should have both...Hope this helps.

easy fix is sometimes the "circuit breaker" in the inside fuse panel, on GM products they are likely silver colored and pull out and plug in just like a fuse. Some car makers have the diagram inside the fuse cover which makes it convenient to see which fuse or breaker applies to the defogger. you can switch identical cir.brkr.s with each other to see if then it operates. then get a new one from your parts store. I switch the power seat relay with the rear defrogger relay and this confirms my check before spending any money. good luck keith

blinkers sounds like the flasher unit is not working. It's located under dash. Also check for burnt out bulbs.
Rear defrost, or rear defogger?: Your defogger for the rear window would run off a relay, probably located in the fuse panel of your car. Often, the connections at the rear window get broke or disconnected.
Front defrost: does your heater blower work?

i would imagine the fuse for it would be inside the car under the dash on drivers side. but also if you look at the rear window you should see the rear defrost wires soldered to the window sometimes one will break off and it might just need to be resoldered

There is a connector going to rear defrost on the rear window. Disconnect this and check for voltage with defrost on. If this is good, check resistance for the connection to window. This will tell you if the electrical is working or the element is bad for the window if there is a open reading on multimeter.

Take your vehicle to the garage who would inspect the car circuit.

yes but it could be the light bulb also turn it on leave for a couple mins feel the back glass if it is warm then its your bilb behind the button if not then its your fuse
