Driver's side passenger power window will not actuate. Neither the console switch or the passenger switch will actuate the window.

Is it possible both switches could be bad? Could the relay be bad? Or the motor? Where would I find the fuse and relay, for just this window?

How do I check to see if the relay is bad? What is the procedure to check for bad switches?

Any advice at all here and the order in which to check the problem would be EXTREMELY helpful as Im running blind awaiting a repair CD. Its getting hot and the A/C is dead and I need to roll this window down!

Thanks.
