2005 Pontiac Bonneville, all of the power windows, power locks and power mirrors stopped working at the same time. Also, when you open the car door the interior lights don't come on and when you turn the car off and open the door the radio should turn off, but stays on. What could call all of this?

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.

Sounds like body control module. Did water get inside the car recently?

Check the owners manual and cover on fuse and relay centers. Look for a blown fuse or bad relay. Then the fun begins. Finding the issues ,if there okey.

1.disconnect each door module ( remove door panel)
2. reconnect 1 at a time.
3. you probably have one shutting down the system

Remove the small triangle panel in the corner of the window, one clip. then to remove all of the door panel you can pry starting at the bottom and work to the sides. once all push clips are off. (they really sound bad when they come loose, but that is normal.) push the panel up to remove the last two holders behind the door handle. You will have to remove these later with a needle nose pliers and slide them back on the door panel before you reinstall. remove elect from block and remove the Three screws holding the mirror. they are 10MM I think. and the mirror will practicly fall our. Or just hit something with it like my wife does and they come off pritty easy.

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

Consult you manual for correct fuse applications and schematic for correct locations for your non-working components. Possible blown fuse.

the contacts in the controls may be coroded

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.
