try removing panel and check for loose or worn contacts, or replace the panel cluster with a new unit or one from a junked unit in good condition if cost is a factor

First check would be for blown fuses. Next i would check for a good power and ground at the drivers door switch. If you find a bad power or ground at the switch, trace it back and look for a broken wire. Most likely place to find the wire would be in the drivers door jam. If your power and ground check out ok, and the switch isn't providing power to the window motor and door locks when pressed, then the switch is bad.

Hi, since these functions are on separate circuits, I would say the problem is either in a connector for the door or the ground point 203, which all 3 circuits are using. I would check the ground first. You can access the ground by pulling up the driver's side switch, unplugging the connector, and checking continuity of the black wire to the chassis using an ohmmeter. If the ground is good, then check for power on the dark green wire. Please let me know what you find out and if you have any questions about troubleshooting.

The most common cause of a single door lock not to work, is a bad door lock actuator (also called a door lock solenoid). Another common problem or cause of door locks not working is simply a bad door lock switch. But as per your problem, power window/ lock switch needs to be replaced.If the door lock fuse blows when door lock switch is depressed, then its quite possible that door lock switch is shorting.Bypass the door lock switch and connect the door lock switch wires directly to each other and then see if the door lock fuse blows with car key in on position.If the fuse is not blowing, then connect passenger side switch to driver side switch and then operate and see if the fuse blows.If not, then driver side door switch is faulty and needs to be replaced.-------- ---------- This will help.Thanks.Helpmech.
