May be a bad motor. Check for power and ground. One wire will have power and the other will be grounded, when you press the window switch down it will be reversed, It grounds through the drivers switch.

2002 Cadillac escalade driver side windows don't work but passenger windows do work. The drive side ones quit all of the sudden and also my radio doesn't turn off what is my problem? And how do I fix it?

Right side of the vehicle has a different power supply then left side . Two relay's . RAP #1 & RAP #2 . The RAP #1 relay supply's power to the radio an driver side power windows . I think maybe you have two different problems . The radio not turning off, maybe caused by the RAP relay having stuck contacts . Driver side windows not working , could have broken wire inside the flex boot from the body to the driver door .
Rap relay #1 is located in the left instrument panel fuse box .
Fuse Block -Left I/P
On the lower left side of the I/P
The RAP #1 relay is turned on by the BCM - body control module . Could have a DTC - diagnostic trouble code stored .
Do you know how to test automotive electrical circuit's use a wiring diagram an a DMM - digital multi-meter ? Pull the driver door panel off an check power an ground circuit's for the driver window switch . Free wiring diagrams here Enter vehicle info. Year , Make , Model an engine . Under system click on body & accessories , then under subsystem click on power windows . Click the search button then the blue link .

2010 chevy silverodo driver's power window wiring diagram

I'd check the wiring harness on hinge side of driver door. Probably has a protective covering, see if you can move the covering back far enough to access wire colors. Red wire with white tracer is voltage for power window. Black wire is ground, use a test light and check them both.
You can check ground using a test light, one end of test light touches voltage, the other end touches the ground wire. The light will come on if the ground is ok. It shows the ground is good enough to turn on the test light, at least.
Two wires for window motor one is dark blue, the other is brown.
I realize you asked for diagram, at the moment, this is the best I can do.

Why does power window on left side make a clicking noise and right side does not work at all?

The power window has vinyl gears and a cable that operates the windows. Sounds like the gears are slipping on the one side. The loose wires are going to need repaired to get the other window to operate. You have broken wires in the door. You can take the door panel apart. You will take apart to replace the window gears anyway, so while apart, find and repair the broken wires in the cluster running to the hinge area of the door.

It can be either switch or any of the wiring in between. You have to follow a wiring diagram to test the circuit and this one is a bit complicated.

I need a diagram for a 2002 windstar. the power drivers window does not work and my husband put the whole new contraption inside the door and it will still not work right. goes down but not up. fuses are...

Moving only one way is usually the sign of a bad switch or a wiring issue, not the regulator/motor. It's usually the master switch that goes bad since it's used most often. You can't bypass it because the power and ground both run through it.
