Question about 2004 Pontiac Grand Prix

Where is the rear defroster fuse

My rear defroster is not working at all. The button in the inside will not come on. I look for the fuse in the fuse box on the right side panel of car. But still can not locate fuse. Could you explain where it is exactly at.

It's probably not a fuse, but a relay, also called "defogger relay", and it should be in the fusebox you are looking at, or else in the power distribution center by your battery.
Often the problem with the defroster is either the connector at rear window, or the little bands, or lines that carry current become scraped and lose continuity.

Hi. IDK what you are working on but these circuits are all on accessory power. I would take a look inside the power distribution box first. Look for a blown maxi fuse for the BCM or another remote located fuse block.

Rear defrost not working on 2004 Impala

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.

Rear defroster inop

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

I have a 1990 Ford Taurus and my blinkers don't

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.
