Hi
I have a '91 3.0, and have been having some trouble with the passenger power window switch. The drivers control switch that controls it doesn't work either.
I have taken both switches apart, and I cannot see anything obvious.
I was just wondering if anyone else had ever run into this, and if i am missing something important.
thanks
Mark
p.s. does anyone know the wiring color codes for the wires leading out of the main drivers switch assembly?

 

I have some PDF files on my server from the factory CD for our type of rigs.

Before you go ripping things apart, read this.
This too happened to me a few years back.
I could not control the front passenger window with the master drivers switch, but it would work once in awhile with the passenger one.

This would make you to automatically think it was the drivers side switch.
Not so...

To test this, take out one of your rear window switches and swap it to the front passenger one.
This cured my problem, and I ordered a new switch.

See if that works for you first.

Man, your a lifesaver. It worked perfectly. I leave for vancouver tomorrow, and I HAD to get my window up before I left (for obvious reasons).
Thanks again.

Glad I could be of help.

When it first happened to me, the dealer swore up and down it was the master switch which is $$$.
They would not let me take out a new passenger switch to test it, so I just swapped mine as mentioned and it was the cure.
