Power window module
 

I'm have issues with the power windows on my 87 928s4. Somebody suggested that the problem might be the the window module. can some tell me where is is. I have looke under both seat and in the center console. If there is one I can't find it. Thanks for the help.

Only 90+ have the module. On cars 89 and prior all the power going to the window motor is sent through the switches. A much simpler system.

The contacts inside of the switches can get hot and sink into the plastic making the windows harder to engage.

Good to Know
 

Thanks for the info, that is what I needed to know. Still not working but I know where to go from her.
