To test the switch, find the hot wire to that windows motor. press the switch and see if battery voltage is present. 12.6Volts on a fully charged baterry. If not then the switch is bad. If battery voltage is present try connecting a twelve volt to the motor supply wire. see if it runs. If it don't then you confirmed 100% that it is bad. In my experience the switch seem to go out before the motor. So more than likely it is the switch.

Tried it today and none of the windows work from master switch on drivers side except ft passenger window, which went down but will not go back up.


You can't put up the front passenger window with it's own switch ? Did you check the POWER WINDOW RELAY in the instrument panel fuse / relay box ? An you checked POWER fuse 30amp same fuse box ? All window switches have direct power from power window relay !

Which Relay/Fuse controls the power windows?


Did you check for battery voltage at the switch , with a volt meter before you replaced the main driver door switch ? Maybe you'll want to take this to pro ,instead of just replacing parts !

Why want my power window on driver side want roll up the other 3 work fine ?


Bad Switch? Bad motor? Get a volt ohm meter out and test for power to and thru the switch. Pull the door panel and check the power and ground to the window motor

I got a 2000 Pontiac trans am and every time I turn the car on the driver side window will roll down and it won't roll back up. But the passenger side window works fine. And when the stereo works the...


How about when the radio is on & the key is off or
in your hand,if you open either front door does the radio go off
& do you lose the delayed window feature assuming you have that
If so you problem is a delayed accy relay
Next would be the front door switches
I will give you credit for what you tried
but fail to see why you would switch motor
from door to door,they work powered directly or they don't
I would think your battery would have gone dead by now
if the relay failed to time out or go to sleep

Why won't the driver side window roll down?


The drivers window gets the most wear. Some cars have a relay for the automatic lowering of the window once it is engaged. This can also mean the push switch for that window does not work to send the signal to the relay. You would also need to test the wires for power from the Relay to the window motor. Once you have eliminated the window switch, the window relay, you are left with the window motor.

The wiring leads from the window motor can be checked with an Ohmmeter to see if the window motor is burned out. If you do not have the Ohmmeter, they are part of a multi-tester which is inexpensive.

Getting the door panels off to do this varies by automaker. A place which could help you would be a Glass shop. They open door frames daily to replace glass.

Also the track that the glass fits in may need adjustment. If the track is misaligned or bad it will strain the window motor or cause a fuse to break.

I hope my solution is helpful.

One day the power window would not roll down but the power locks on the same side work fine.It also will not roll down withe the button on the drivers side.. 2005 GMC Envoy


The power locks have absolutely nothing to do with the power windows - totally different circuits.

The FIRST thing to check is to make sure that the window lockout button on the driver's door control switch is not turned on. This will keep all of the windows from operating except the driver's window.

Other than that, there are several things that can cause a power window to not roll down. It can be a power window lift motor, a window regulator, the window switches, or any of the wiring in between. Also, you did not mention which window is not working. BOTH of the FRONT windows are equipped with Door Control Modules (DCM) which, in turn, are controlled by the Body Control Module (BCM). If it is the front window you are talking about, it will be necessary to scan your BCM for fault codes to determine the source of the problem. If it is one of the rear windows, this can be checked by regular electrical testing and a scanner should not be necessary.

The windows on my 1993 Subaru Loyale won't roll up. last night i rolled down the front Passenger side window and now its stuck. After a little more investigating i figured out that the drivers side...


it could be a bad driver door master switch or bad window motors, the best way to pin point the problem is to remove the door panel off every door that doesnt work and then test for power and ground while hitting the switch, if it has power and ground then motor is no good,start there, another option is to test for power and ground at the switches,

Pass.side power window won't work.


First be sure the window lock in the drivers side master switch is not LOCKED. This will prevent the windows from being rolled down by any other switch. (p106+)

Usually windows operate off a RELAY - not a fuse... and all the windows work off the same power relay.

Your Relay Part Number is 41-5021.
Here is the electrical schematic for your windows - showing the relay is common to all windows.

CLICK HERE for a better pic.

If the relay is replaced - and/or tested good, You will need to remove the offending door's panel and verify the motor is getting 12VDC when you press the button for it to go down.

If there is 12VDC when you push the button, the motor is bad.

If there is NOT 12VDC when you push the button - the master switch or child lock bypass switch is faulty.

Click HERE for a PDF version of your owners manual

Under the ROADSIDE EMERGENCIES section (p.245) you will find a layout diagram of your fusebox.

P.248 instructs to pull DOWN on the fusepanel door to access... however your power window relay is located under the driver's side dash.



If the other windows work - there are 3 options to test/replace - in this order
1. Relay
2. Master Switch
3. Window motor.

Rear side windows


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.
