Electrical problems
Problems. Driverside door lock not functioning. Driver side window not working. Passenger side window not working( now fixed, motor needed a good thumping. Passenger side mirror not working.
I replaced the controlls on the door, no help. Switched the controll box with passnger side one, same results. Anybody have any guesses as to what is causing these problems?

Check your fuses first if door controls appear "dead". Pull your codes and post them all here (hold Options, press Fuel 4 times) so we can diagnose.
When you press the door lock buttons, do you hear a click or "shuush" sound, but the mechanism doesn't move. If you hear action, it is likely bad relays in the DCM module, or sticky lock actuator. Test driver's door controls and report driver's door sounds ("local" controls). Repeat tests from passenger door controls, too.
"Remote" control problems (driver's controls won't actuate passenger door actions, or vice versa) is usually a serial bus fault with exposed wires in the door accordian. Likely the root cause of the passenger mirror inoperability. Or did you not swap the DCM modules back?
Window motors can be debugged with a voltmeter. Unplug the 2-wire harness and measure. If you get +/- 12V when pressing up/down but the motor doesn't move, problem found.

Thanks. I won't be able to get back to the car untill Sunday but I will pull the codes then. The window and lock make no clicking when attempting to opperate. The only thing opperating in the drivers side door is the mirror. All fuses are good, and the controll module is getting power. I will put the volt meter to it Sunday. Thanks Again.
