1G Rear defroster not working

[talontsiboy24]

The rear defroster button wont light up and when i push it in it wont click what can it be? where is the fuse for the rear defroster maybe its blown? is it number 3 10a?

Bad switch try a junk yard for one, i always pick up stuff like switches cars are getting older and harder to find parts for.

So its def the switch huh? I will check the fuse make sure its not blown also check that its plugged in on the rear window havent did those steps yet if all is good there then i know its the switch besides a junkyard will a autoparts store have it or can order it? Dealer maybe?

Its just 1 fuse, possible auto store no, dealer , maybe or maybe not, if so could cost you. Best bet jun yard or ebay, try there, or look on part outs email them or call them they may have one, look around. I may have one laying around.

I have a spare from a 99 RS if it will work I’ll give it to you if you pay for shipping.

Well let me check the fuse and make sure everything is hooked up for the defroster and i will get back to you guys. Maybe i just gotta push in the buttom a lil harder will see.

I have a similar problem with my GS. It only turns on if i push the button on the bottom right corner instead of the middle
Idk that might work for you

 

[talontsiboy24]

I checked it out and everything looks fine so the only reason i see why its not working because when i push the button in it doesnt click just pops back out so i need a new switch right?

Thats what it sounds like your switch is bad.

in a 1G, the rear defrost switch is momentary. So even if you were to replace it with a brand new one, it will never 'click' or latch into an on position.

1G's seem to have a problem with the rear windshield's defroster's electrical contacts breaking off of the glass. I would check them first. There are two on each side of the rear glass about 1' away from the rear gas struts that support the hatch lid.

If you have already verified that all contacts & fuses are good, I'd look into the rear detrost relay (located in the engine bay, next to your injector resistor pack).

the rear contacts on the window are plugged in and are on each side and the fuse is not blow so i think its gonna be the relay then?

..switch loves to get sticky after awhile. I have to tap on mine a couple of time to latch.

Several years later and im running into this probelm. Where is that relay!? I cant find any pictures or nothin anywhere! I had to resolder on my contacts on the rear window and yet that did t work. Ive tried two different defroster buttons. None light up or engage. Fuses are fine? So last thing to check is the relay.

For the 1g I believe the relay is located on the engine bay firewall right behind the battery. The relay is on some wires coming right out of the main harness.

Sorry, my post 14 must have been for the 2g.
