What could cause my power locks and windows to not work replaced master control window switch Thanks

if more than one power window not working you have blowed fuse or you have window on lock out mode on the master control switch on the driver side.if master window control switch on driver side wont work but 2 windows will work using their switch the master control switch on driver side is bad.

Check your fuses for power windows if those sare fine take a test light and see if your switch is getting power to and from it.Could just be a bad switch or motor

Hi,
This is usually cause through a central switch system which is the master window control on the drivers side.
Have the drivers window control assembly checked and tested, it may need replacing.
Thanks

Replace the drivers door control panel

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.

check your window lock out swich on the drivers door if locked out or broken it will not lut passenger windowes ip or down

replace the power window master switch and chances are the lock actuators are bad. replace as neccessary. happy holidays

TRY THE WINDOW LOCK SWITCH ON THE MASTER CONTROL AND SEE IF OTHER CONTROLS WORK.
THE SWITCH IS NOT SERVICABLE REPLACED AS A UNIT.

page 3-39 in owners manual. automatic door locks. do the steps and change too lock 2. this worked on my 2006 colorado crew cab. good luck

This may be just a case of inadvertently hitting the window lock out n th driver door window switch by mistake. Check that first. Here's some background on window operation

Principles of Operation
The driver power window regulator motor is controlled directly by the master window/door lock/unlock switch (and its integrated "auto down" module). Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The driver power window regulator motor is a reversible motor that is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The passenger power window regulator motor is controlled directly by the passenger power window switch and can also be controlled by the master window/door lock/unlock switch. Power is supplied to the power window relay and the master window/door lock/unlock switch, and the passenger power window switch when the SEC/timer module grounds the coil side of the power window relay. The SEC/timer module will ground this relay when the ignition is in the ON position and will remain energized for approximately 15 minutes or until the driver or passenger door is opened.
The passenger power window regulator motor is a reversible motor, which is operated by applying power and ground to the motor leads to lower the window, and then reversing polarity on those leads to raise the window.
The power rear quarter glass is also directly controlled by the master window/door lock/unlock switch. The power rear quarter glass power latches also utilize reversible motors. The power rear quarter glass power latches are operated by applying power and ground to the motor leads to open the window, and then reversing polarity on those same leads to close the window.
