Both driver side power windows do not operate when I hit the power window control on the driver door. However, both passenger side windows operate properly. The electrical gauge does move slightly when I hit the non working window switches. The car has not been used in about eight weeks. Any idea what the problem might be?

Does the driver's side rear window work from the rear switch?
Did both the windows quit all of a sudden and, most importantly, at the same time? Please advise.

Answering to your response regarding my power window problem, this problem did occur all of the sudden. Also, the driver's side rear window does not work from the switch on the door. Please advise.

Sorry it took so long to get back to you. The online responses have been a little crazy lately. I was at the keyboard until 2am this morning. We old guys need our beauty sleep.
Looking at your wiring diagram, it shows only 1 circuit breaker feeding the system. If the 12 volt source from the driver's switch cluster is interrupted, you will lose all control to the rear windows, even at the rear switches. I have to believe, the problem is in the drivers's door switch pack. If you have, or have access to, a fax #, I can ship you the diagrams so you will better understand what I'm saying. Please advise.

Would it be possible to mail those diagrams to my home address if you have it on fille? I would rather not have them forwarded to my work fax. If not, could they be forwarded thru my e-mail?

I received the wiring diagram. But attempting to print it out in a readable clear image has proven unsuccessful. This repair is beyond my ability and I will have to have my mechanic repair it. I will pass along the information you have provided me and sincerely appreciate your help. If you could find someone who can place the diagram in such a way that it appears on an entire page in a landscape, not a portraiit size, it may be readable. Perhaps attaching it as a PDF within an e-mail would be the way to do this. Ask a computer geek and I think it could be done easily. Please e-mail me if this works. Thanks again.

Roman, thanks for your response. I have trying to get the company to alter their system to recognize PDF files. It would be much easier for us and be a better service for our posters. The PDF file system is a FREE download from the internet and sooooo much clearer and faster. I'm going to try a new approach on your diagram. I'll get it out ASAP.
