None of the power windows on the vehicle work. Is it the power lock that is stuck and how do I repair it?

If none of the power buttons on your 2004 Pontiac Grand Prix are working, it could be caused by a few different issues. Here are a few possible causes and solutions:
Fuses - There may be a blown fuse related to the power windows or door locks. Check the fuse box and replace any fuses that are blown.Relay - There may be a relay that controls the power windows or door locks that is faulty. A mechanic will need to diagnose and replace the relay if necessary.Wiring - There may be a problem with the wiring that connects the buttons to the power windows or door locks. A mechanic will need to diagnose and repair or replace any damaged wiring.Switch - The switch that controls the power windows or door locks may be faulty. A mechanic will need to diagnose and replace the switch if necessary.Body Control Module (BCM) - The BCM (Body Control Module) may be faulty which controls the power windows and door locks, and other features on the vehicle. A mechanic will need to diagnose and replace the BCM if necessary.It's important to have the vehicle inspected by a qualified mechanic to diagnose the problem and perform the necessary repairs. Some of the issues can be easy to fix, but some require more extensive repairs and knowledge of the systems.

No ,not a fuse ,has a circuit breaker . They rarely go bad ! I looked at a wiring diagram to see what could be causing your problem . You have no power to front windows or locks ? Where did you test ? the switch ? Where ? You need to know how the system works before you can test , an a factory scan tool is essential ! Your switch is a low voltage signal to the door modules ,an the DDM - driver door module is connected to the PDM - passenger door module on a serial data network or data bus as it is called ! Your best bet is to take your vehicle to the dealer or a ASE certified repair shop , Because you lack the knowledge an tools to fix this !

When you push the driver door master lock switch , none of the locks work ? Not from any switch in the vehicle ? What year is your vehicle ?

Seems verry likly that the lock switch has stuck in the lock position and will most likly need to be replaced. Unless you are able to remove and spray with a contact cleaner

what is the year make and model of your vehicle?

The first thing to do would be to hook up a factory or professional type scan tool an check for DTC'S - diagnostic trouble code's . This vehicle has very complex electronic's. Serial data communication network,class2 data bus . There are electronic modules inside the door's that control the lock's ,power window's , power mirror's . Your best bet ,take it to a qualified repair shop . Not a fuse problem , driver an passenger door module each have thier own power supply. Two circuit breakers ,PWR/WDO circuit breaker 30 amp. You could check DRVMDL 10amp fuse ,located in the rear fuse box , PASSMDL 10amp fuse rear fuse box , RRDR/MDL 10 amp fuse rear fuse box . Rear fuse box is under the back seat . None of the window's , lock's etc.. work from any door switch ?

First, check all fuses to make sure that none are blown.

If the door lock switch works on the passenger side, then the drivers side door lock switch is probably faulty. Use a multi-meter to test the Drivers Side Door Lock Switch (Black and Pink/Light Green wires unlock the vehicle, and the Black and Pink/Yellow wires lock the vehicle)
If the switch is tested and found to be operating properly, you may have a faulty Body Security Module or Drivers Side Door Lock Actuator.

If neither of your Power Mirrors are working, you probably have a faulty Exterior Rear View Mirror Switch, Power Mirror Module, or blown Central Junction Box Fuse.

If none of your Power Windows are working, you probably have a faulty Accessory Delay Relay or a blown fuse in your Central Junction Box or a faulty Master Window Adjust Switch (all of the Power Window Switches feed through this Master Window Switch). If the Power Windows didn't stop working at the same time, you may have faulty Window Adjust Switches, or faulty Power Window Motors, this is very unlikely though. It would also be a good idea to inspect the wiring for any obvious damage.

The power door locks and power windows in your vehicle are computer controlled. Each door has a computer module in it which operates the door lock actuators and the power window motors. All of the modules are connected together through the Class 2 data circuits. A scan tool capable of communicating with the body control computer systems in your car is required to properly diagnose and repair your door lock system.

if your window is stuck open you can close it from the outside. put the key in the door lock and turn it to the right until they all close. My cabrio is doing the same thing and that's how I closed mine.
