In my 2003 AV the passenger power window stopped working. In the manual it indicates the window has a circuit breaker, not a fuse. Does this circuit breaker have a reset? Manual or automatic? Or do you replace it like a fuse? How to check the function of the circuit breaker? Thks!!

Passenger window circuit breaker

As you read this clip from GM, you will see that the breaker is a self-resseting type.
"Power Windows Description and Operation
Power Window System Components
The power window system consists of the following components:
* Driver Door Module (DDM)
* Passenger Door Module (PDM)
* Body Control Module (BCM)
* RR power window switch
* Window up and window down relays in each of the rear passenger window switches
* Window lockout switch
* Reversible power window motors in each of the doors (circuit breaker protected)
* LT DOOR CB 25A (System power for left windows)
* RT DOOR CB 25A (System power for right windows)
Power Window System Controls
The power window system will operate anytime the Retained Accessory Power (RAP) system is active or when the ignition switch is in the ACCY or ON position.
The DDM contains four power window switches which are integral components. Closing any of the normally open, rocker type switches provides the DDM with a request for power window operation. The switches for the two front windows have three positions UP, Down and Express Down, while the switches for the rear windows have only two positions, UP and Down. Each of these switches and their positions is a direct input into the DDM. Upon receiving a request for power window operation, the DDM, transmits a Class 2 message indicating the switch and it's changed position.
The PDM contains a single power window switch that is an integral component. Closing of this normally open, rocker switch provides the PDM with a request for the front passenger power window operation. The switch for the front passenger window has two positions Up and Down. Each of these switch positions is a direct input to the PDM.
The two rear passenger doors have there own switches. Each of the switches contain a power window up and down relay. A switch activation alone can control the up and down functions of the rear windows. However the BCM, upon receiving a Class 2 message from the DDM, can control the set of relays which will activate the rear window motors.
Power Window Motor Operation
A permanent magnet motor operates each of the power side windows. Each motor raises or lowers the glass when the motor receives voltage. The direction the motor turns depends on the polarity of the supply voltage. The power window switches control the polarity of the supply voltage. A built-in circuit breaker protects each motor. The circuit breaker opens when the switch is depressed for a extended period of time under the following conditions:
* The window has an obstruction.
* The window is fully open or fully closed.
The circuit breaker will reset automatically as the circuit breaker cools.
Driver Power Window Operation
The switch for the driver power window has three positions UP, Down and Express Down and its position is a direct input into the DDM. Upon receiving a request for power window operation (switch activation), the DDM supplies voltage to the power window motor left front up or down circuit and grounds the opposite and the power window motor runs to move the window up or down.
Front Passenger Power Window Operation
The switch for the front passenger power window has two positions UP and Down, and its position is a direct input into the PDM. Upon receiving a request for power window operation (switch activation), the PDM supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to drive the window up or down.
The front passenger power window can also be controlled from the power window master switch. The power window master switch for the front passenger power window has three positions UP, Down and Express Down and its position is a direct input into the DDM. Upon receiving a request for front passenger power window operation (switch activation), the DDM transmits a Class 2 message indicating the changed switch position. When the PDM receives this message, the PDM supplies voltage to the power window motor right front up or down circuit and grounds the opposite and the power window motor runs to move the window up or down."
If you hear an occasional click, there's likely a short, if it's stone dead, likely a motor. BUT there are other factors still...
(I presume your other pass windows work...)
If it's in warranty, take it in!!
Otherwise, pull the panel, remove the motor connector and use a test light/meter on the source connection while you operate the window. At least one way should light (depends if it's at limits or midway). If so, it's a bad motor but check it with the motor connected again just to be sure. If it doesn't light (be sure of the test light connection), you could have a bad module, shorted motor or a resistive power source connection. A diagnostics tool should show module or signalling errors, but it depends on the tool's abilities!
Site unseen, it's quite limiting what one can do to help!
I'll see if I can find a print..

What ever happend to just up and down switches. The more CRAP GM puts in there stuff The worse they get.....
Why don't they learn from the past....

Agreed, What ever happened to the KISS Principle?
Actually, the idea is to reduce the wiring. Instead, it increased the headaches!

Sperry,
Great info, thanks a lot.
There is a click when trying to operate the window, so for now I'll asume there is a short somewhere. (maybe why the radio mysteriously quit workng for a few hours last week??) Warrany is gone (45K miles). Short of just inspecting all the wires, is there a good starting point? I am not the best at electrical troubleshooting. Maybe worth a trip to the $$dealer$$. Thanks!!

As you see the breaker is in line with both windows on the right. If you operate the Pass window and it clicks, the RR window won't operate if it's the relay clicking (until it resets). If it (RR) will operate during your Pass window attempts, it's not the breaker or source power. Instead, you'll have to trace the immediate wiring (or the exclusive power tap for the Pass window).
Here's the door trim removal: (They only show the Driver Door.)

what year is your description for SPERRY?
2002 is different then 2003+ I think....

Here's a better door panel rem view (and the Rt side!)
Well, the passenger door lock switch works, as do the rear windows. Passenger seat heaters ok, too. The window is the only problem. From you post, I understand to start with the wiring inside the door- correct? Thanks again - the drawings are a huge help!!
to help! At least when I can, and also have the resources!HTH!
Had a similiar problem with my 2002 AVA--The trouble was in the driver door master control--a simple loose wire on the switch--push fit and all has been well.
Just pull the plastic switch plate off the door--use a plastic pry as not to scratch the panel--have a look-see.Push in all the wire connections to the spades--while apart--try the switch at the driver and pax door.
Good luck
Clare

Did we find a fix?
It seems I am having a similar problem with my AV for the first time. My front passenger window will not go down, it clicks but nothing else. Door locks work as does the Rear passenger side windows, etc. Its still under warranty and I think I might just take it in, I am not to electrically inclined.

better to take it in...
if you hear it click in door panel something else may be wrong

My front passenger side window also clicks when it's operated from the Drivers side, but not the Passengers side. I assumed that there was some sort of relay involved, similar to the horn. The rear windows don't do it, however.
Kirk: "How did you do it?"
Scotty: "The more they overwork the plumbing, the easier it is to stop up the pipes."

As you see, the 02 & 03 are different. What "M.Y." is yours?
Well she is scheduled to go in tomorrow morning and they won't even give me a rental. Oh well, looks like I got to rent one on my own.
Oh well, looks like I got to rent one on my own.Got the window working now. The dealership just changed the motor on the electric window dilly whopper.
