I own an 86 GT and since i've owned it (only a couple months) the windshield wipers don't work. The person who sold me the car told me it was the pulse board. The board that was already in it was burn't up, and when i replaced it with a remake from Oreillys it burn't it up that very same day. I have a 20 amp fuse in it, that was what my manual stated should be the correct fuse. I have been trying to find a good spec blueprint but i haven't been able to. Has anyone had this problem before? Any advice would help a lot,

Thanks

FWIW, the purpose of a fuse is to protect the wiring, not the devices connected to it.

sorry for the wait


A few days ago i tested a new board exactly like the one that was burnt up when I first replaced the board. I put in the 20 amp fuse and turned the key enough for the battery to come on. Then I put the wipers on high for about 5-10 seconds and then turned everything off. I felt the board and it was extremely hot but not burnt up yet. After that I just turned the key but kept the wipers off. I could see smoke coming up off of the board. After that I took out the fuse and the board and took it back and got my money back.

The board in the picture is the board that was in the car when I bought it. It was already burn't up when i got the car. I don't know if the board is the original board that came with the car.

I was hoping to see something more obvious.....you may want to check the motor for an internal short.

Thats a good idea and i thought about doing that but I read the only other post on here with this topic and the person tried replacing the motor and it still didn't fix the problem...
I took the motor all the way out of the car a week ago but there is no way to take it apart without drilling through about 10 rivets

It would probably easier to just go to autozone and buy the motor and test it out with a new board.
If it still burns through the board i can just take the motor back and get a refund

I'd put my money on the switch in the column being the problem. I have a thread on here regarding my problem with a phantom wipe that eventually progressed to a complete failure. In my experimenting and diagnosing the problem which turned out to be the switch in the column I arrived at the conclusion that the malfunction in the switch burned out the board as the later model replacement board resulted in an immediate failure of the fuse repeatedly where before the board burned out instead. I've had no more problems since the replacement of the switch inside the steering column. 86SE
