Power windows won't work. Ideas?

I am trying to help a friend get the windows working in his 77 Buick Century. Anyone know were to find a diagram for the wiring? Any suggestions?

 

Tell him to buy a chassis service manual for th 77'. It has diagrams of almost everything. Goodluck!

 

Something to remember here...the swirches on these armrests act as part of the circuits whether static or being used. Since the driver's switches are used the most, it would be the place to check first when tracing voltages. A chassis manual would certainly beat the price of unnecessary parts. It is my suggestion as well.

 

Thanks, I'll pass that on. Sean.
