Override power window switch

bad switch

1) Master power window switch on the driver door may be bad.
2) Make sure the passenger door master switch has the passenger door switch enabled. If the switch on the passenger door wont raise the window, you probably have a bad window regulator. If it raises the window then the master switch is bad.
3) If the window makes noises when you use the switch and doesn;t raise, then the regulator is bad, Check EBAY for sales, that's where you or your mechanic can find them...Chris

Test the MASTER switch at the drivers side. It seems to be a "wiring problem with the Master switch. The master switch is the switch that controls ALL the cars windows.

The passenger window switch gets both power and ground from the master switch. You have replaced the passenger side switch and it still had the same result and if the wiring is good from the master switch to the passenger side switch, then the only thing left would be the power window master switch. Check all wiring of the Master switch. That's the only thing that's left to do.

This may be related to the BCM (body control module) it can be self tested to see if any faults are present.

There could be a lock controller somewhere that is not working.
I don't have a wiring diagram for your truck.

Generally, the power window motors are grounded thru the doors, or the switches provide ground. In your case the motors are probably grounded thru the doors.
The master switch "overrides" the door switch so you have extra wires that do the same thing. The E wire probably gives the door switch power and the A and C are up and down. The B and D are override circuits from the master that bypass the door switch.
Sometimes the motor is grounded thru the switch then thru the door.

Try a passenger side door switch or a new complete master switch on drivers door. Alaways check fuses also.

The lock switch is designed to keep the passenger buttons from being used. It should not stop the master switch from operating the windows - or at least, that's what the 2003 Buick Century Owner's Manual says.

After studying the schematics for your vehicle, Iwould say that the owner's manual is correct. The lockout switch only cuts power to the passenger switches. The driver's (master) switch can still power the passenger windows. If none of the passenger windows work from either the driver's door switch or the passenger switches, then the master switch probably has an internal open circuit causing this. There is no separate relay or fuse. I would replace the master switch. Be sure and check ALL switches with the lock on and the lock off to verify this before replacing anything.

Make sure the window lockout button is not depressed on the master window switch. This will turn off the other switches and not let them control there respective windows.

Power is supplied to all the windows from one fuse and one relay. So if the master switch operates the window than we know the fuses and relays are o.k. We know the master switch will operate the window so that tells us the window motor and ground side of the passenger window motor circuit are also good.

Which leaves us with a bad switch or no power to the switch. The passenger window switch gets its power to operate independently from the master switch window lockout button. When the button is off power is supplied to the passenger switch and allows the passenger to operate the window themselves.

The only thing you need to do is check for power at the passenger switch on the brown wire with orange stripe. If there is power there then you have a bad switch.

Your switch itself may have been the problem. The master switch in the drivers area can override the passenger switch.

sugest fuse ck 1st thing. Master bypasses individual controls. Power supply to rear windows is interupted. Ck for connevtor under front seats. Fuse may be labrled accessory or per win.
