Power windows Quit Help !

[72MARIO]

I went to put the windows up and the stoped working. It's a 87 Burb. Also the back window does not work either.

Any help would be great.

Mario,

Go to the fuse block and you should see two small aluminum boxe's one is for your window's and the other is your pwr. lock's
if you have them

Now swap them and see if the lock's quit working and the window's start working if so then replace the bad aluminum box.

The aluminum box is not a fuse even tho it's rated @ 30A.

It's a self reseting breaker that opens when it overheats due to too much current draw and then it reset's when it cool's off.

If you replace it with a new one and you still have a problem then you have either a bad motor or faulty wireing causing the breaker to open.

Then you will have to start unhooking each door motor 1 at a time untill you find the bad one.



But they go bad.

You might also check the power door lock/window relay, but that's what 87 Stepper might be describing.

A duh question but sometimes it works - have you tried looking at the power window fuse?

Thanks.

The power feed plugs into the fuse box in the accessory terminals at the top. My wife some how managed to kick the fuse box and knocked it out one time on our blazer.
