Question about 2003 Pontiac Grand Am

1 Answer

Power windows all stopped working

None of the power windows work from any of the window controls. None will roll down. 25a circuit breaker tests good from passenger side fuse box. Pulled the window switch off of the driver side main control. Tested the copper on the switch and it seemed to test good. Maybe the switch is bad? Any other possibilities? I don't have the money to throw at random parts...

Maybe a broke wire inside the rubber boot from the body to the door ! See this a lot. Opening an closing the door a million times . Do you have a volt meter ? Pull the switch from the door an test for B+ voltage on the brown wire at pin G connector 1 The other window switches get B+ from the drive door switch . Also check the ground , black wire pin B connector 1 . Do you know how to use a DVOM - digital volt ohm meter ?

2004 Yukon Power window, fuse blown which one

94 Corvette. Windows don't roll down or up button on Side door not working either. Hatch Button works on Center Console. Are there fuses under hood causing this? The Stereo Amp behind Seat BAD, water


Are there fuses under hood causing this? Without looking at wiring diagrams to see what all is involved in the power window electrical circuit would be guessing as to what the problem is . An looking at a wiring diagram I see a circuit breaker supply's B+ voltage for the window's . Circuit breakers very rarely go bad . I would look for broken wire's inside the rubber flex boot from the body to the door. Or maybe the power window control module is bad . If you know nothing of automotive electrical systems , wiring diagram's ,an how to test with a DMM - digital multi-meter ,your best bet mite be to take it to a qualified repair shop .

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)

?€¢
LR power window switch

?€¢
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 rear window)

?€¢
RT DOOR CB 25A (System power for right rear window)

Are you aware of the electronics involved ? control modules - computers ? Are you good diagnosing electrical problems . Do you own a professional scan tool ?

  1. Install a scan tool.
  2. Monitor the Driver Window Status Data parameter in the driver door inputs list.
Does the Driver Window Status Data parameter display an active state?
Your best bet would be to take your vehicle to a qualified repair shop . For both problems .

Are all windows not working ? Two separate circuit breakers left & right . Both in rear fuse box . Fuse Block - Rear Beneath the left rear seat
Check for broken wires inside the rubber boot from body to doors.
Do you know about electronic control modules ?
The power window system consists of the following components:

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 4 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 2 front windows have 3 positions Up, Down and Express Down, while the switches for the rear windows have only 2 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 2 positions Up and Down. Each of these switch positions is a direct input to the PDM.
The 2 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.

My 97 GMC Drivers window goes down but not up. If it turn the power on and off it will roll up, however when it goes down the "auto" kicks and and wont stop. When it reaches the bottom the...


With some makes and models, there is an auto down module for express down, it can be part of the driver door master switch.
With express down, when the window gets to the bottom, the module may sense over current, then interrupts voltage.
On some vehicles that had problems with window motor, I have touched power window circuit breaker, this one was metal, hot as it could be. The circuit breaker will trip when it gets hot and none of your powers will work. Once the circuit breaker cools down, it may reset and the windows will work again.
If you bench tested the new window motor on the bench, with jumper wires to battery, It will probably run as long as the jumper wires are hooked up, nothing to shut the voltage off. Just my opinion.

The windows operate off a window relay amd a circuit breaker only. The circuit breaker is in the fuse box and it is made with a metal housing

Electrical problem


Instrument cluster problem maybe . Without testing we'd only be guessing . Have seen this a lot at the dealer . The best thing would be to hook up a factory scan tool an check for DTC'S - diagnostic trouble codes first. The electronic's on these vehicles are complex to say the least . All the warning light's , gauge's etc.... are controlled by a module an data network . GM class 2 serial data buss. Power windows also are controlled by a module . DDM - driver door module.
