Question about 2003 Buick Regal

1 Answer

2001 Buick Regal. Power door lock swith will not lock doors.

I have a 2001 Buick Regal. The driver's side door power lock switch will not lock the door. The switch will unlock the door. The keyless remote also works with locking and unlocking the door. The passenger side power door lock will also lock and unlock the doors. I tried replacing the Power lock swith on the driver's side door, but everything works the same, no change. Any good advice?

    1. Where is the master control switch located? 2. How would I know if it is just a faulty/loose wire?

Remove the door panel and unplug the connector to the door actuator. Probe the contacts with a voltmeter set on DC volts. Then operate the lock/unlock switch. You should see the voltage toggle from +12 volts to -12 volts. If you do, then the wiring, switch and connector are good and you have a bad actuator. Be prepared to start replacing all of them because they all operate the same number of cycles.

The only way to really see the problem is by removing the door trim panel. This will allow you to see if is the actuator is moving, and how far, along with noting any interference of lock linkage movement. Hope this helps.

Passanger side doors wont lock


From where , any switch ? driver door switch or either passenger door switch . This is a very complex system controlled by modules (microprocessors)
?€¢
The driver door switch assembly (DDSA)


?€¢
The driver door module (DDM)


?€¢
The passenger door module (PDM)


?€¢
The rear door module (RDM)


?€¢
The LH front power door lock switch


?€¢
The RH front power door lock switch


?€¢
The LH front door lock actuator


?€¢
The RH front door lock actuator


?€¢
The LH rear door lock actuator


?€¢
The RH rear door lock actuator


?€¢
The remote control door lock receiver (RCDLR)


?€¢
The power door serial data circuit


?€¢
The class 2 serial data circuit


?€¢
The DRVMDL Fuse - 10 amp


?€¢
The PDM Fuse - 10 amp


?€¢
The RRINMDL Fuse - 10 a
Class 2 and Power Door Serial Data Links
The class 2 and power door data circuits are both serial data links. The serial data circuits replace cables in the vehicle by multiplexing (time-sharing) data to and from each device over a single wire referenced to ground. If the power door serial data is lost, both the rear door module (RDM) and the passenger door module (PDM) enters the sleep mode. With the RDM and the PDM in sleep mode, no power door operations are possible.
Your best bet is to take it to the dealer or an ASE certified repair shop .

I have a 93 buick regal but my front doors & rear


Well, the mirrors would be on the circuit with the courtesy lights. The door locks and windows would be on different circuits.
Why can't you unlock the driver's or passenger door with the key and open it with the door handle ?

Winow goes down won't go back up. swith is


There is no type of sensor in that system, however the problem could be a broken wire inside of the weather boot that runs between the door and the body of the vehicle. (The broken wire(s) will most likely be inside of the driver side door weather boot, but it could also be inside of the weather boot on the door that has the window problem)

If the window does go part of the way back up then most likely the window regulator assembly or the drive gear between the regulator assembly and the power window motor is damaged, and the door panel will have to be removed to inspect for the actual problem.

Here is a wiring diagram of a typical power window circuit for that year and vehicle to help assist you.
