I had this problem where only the drivers door power equipment works.

It is caused by a splice under the driver's seat. Spice #S302 where the input from the drivers door module to the other door modules connects. It is one of those cheap *** splice that should be outlawed. Moisture gets in it and corrodes. Cut back the wires till you get the good stuff and redo it the right way.

Splice S302 can be found under the carpet about six inches before where the wires go up to the drivers seat. It is in a plastic wrap and tape. I believe the wires for the window are brown and white.

Take a good look in wiring harness that runs through from drivers door into pillar at door hinge area. Was always a good spot for wires to corrode, or break from opening & closing door. Obviously the drivers door is usually first to experience this as it is used more.

2001 Pontiac Bonneville Power locks and power windows dont work

Your power windows an door locks are controlled by a door module .
The vehicle is equipped with power windows controlled by the door modules. Each passenger door power window can be operated, either from a switch built into the driver door switch assembly (DDSA), or from a switch mounted locally on its associated door. The driver door power window can only be operated from the driver door window switch built into the driver door switch assembly (DDSA).
When the driver door module (DDM) receives a window switch request from the DDSA, the DDM checks the Class 2 serial data to see if the status information is correct (i.e. ignition switch position) to permit window operation to occur. If the status information is correct, the DDM, either supplies power and ground to its associated window motor, or, if the request is for one of the passenger windows, sends a command via the power door serial data circuit to the passenger door module (PDM, LRDM, or RRDM) controlling the window. The passenger door module (PDM, LRDM, or RRDM) controlling the window then supplies power and ground to its associated window motor to move the window as requested.
When one of the local window switches mounted on one of the passenger doors is operated, the associated door module examines the request and checks to see if there are any messages from the DDM prohibiting the movement. If conditions are correct, and no prohibitive messages have been received from the DDM, the associated door module then supplies power and ground to its associated window motor to move the window as requested.
Your best bet would be to take your vehicle to a qualified repair shop !

Why doesn't my 2000 chevy blazer power windows and door locks and remote mirror doesnt work. Power window on passenger side does work

well, the first thing is to check the fuses and or relay for power windows.should be listed in your owners manual. if ok, then remove switch from drivers side window and check for power. if power to the switch then use a jumper wire from power side to motor side of switch. if window works then its the switch causing the problem. Good-day!

Only the drivers door window and lock works on my 2000 bonneville none of the others work at either drivers door or any door

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.

Power locks, mirrors and window problems

This is a typical GM problem, most likely are broken wires on the driver's side door. Every time the door is opened and closed, the wires running from the door to the car body flex. Over time these wires break and cause loss of use for power options like you have. It could just be coincidental that they broke in a rain.
There could be other electrical problems such as relays that have become wet and failed or a wide variety of other solutions. Electrical problems never have only one answer

Pontiac bonneville/electrical problem

After checking fuses your only sure hope is replacing the BCM module in the passenger compartment. (Body Control Module) . It runs all the electrical systems...basicly its the engine computers counterpart. Unfortunately mine cost 500 bucks, but it restored all the funky systems that were not functioning. ...cski
