The driver's side window stopped working.  Fortunatly it is up.   It works intermitently, mostly right after I start the car.   I have a service manual, but the electrical stuff has me confused.  Does anyone know how to diagnose the problem using the service manual?

 

That happened in the 350, I ended up taking the electric motor apart and cleaning out dust inside the motor, worked great after that.

I would bet either switch or motor as Chris suggested. If you're not in a hurry I bet I could figure it out with your manuals.
