GM-GMC: 1984 G20 wire diagram, e mail address, side switch

Question
Hello Harry, I'm trying to resolve a problem with power windows on my 1984 G20 van. The right window goes down and up when using the driver side swich. It goes down but not up when using the passenger side switch. The left window is funcioning properly. So far I replaced the up/down switches in both doors and the right window motor.
A wire diagram of this circuit would be of great help. I have diagrams for 1980 light trucks which include G models, but there are many differences in 1984 wiring.
I would greatly appreciate any help you can provide.
John

Answer
John,

I have wiring diagrams from the 1984 GMC Light Duty Truck shop manual, but I have no way to attach them.

I will not list an e-mail address for obvious reasons.

I suggest that you try to contact this site's administrator and ask them to relay an e-mail address that I can send the diagrams to.
