Why not look for the proper switch at the junk yard?  The same switch was used on many GM cars.  Sorry...I just personally hate shade tree modifications.

Override power window switch

Try the switch on the pass side door. Otherwise you need to remove the drivers door panel, access the switch, print a wiring diagram and jump power to the window motor with a jumper wire.

Pass side fuse box dead after arching the battery, no power

Chances are its one of the fuseable links at the starter. The car gets some of its power thru those wires. They look like regular wires except they have an internal fuse. You may need a wiring diagram to figure out which circuit is affected.

1997 chyrsler town & country passenger window won't go up or down

Hi Jack,

First I want to appologize to you for not getting back to you right away. I was not actually online at the time that you purchaced my services. I had simply forgotten to log out. So I am just now getting the message that you have asked for my help.

Anyway, if your other windows are working, this eliminates several possibilities. Your passenger window circuits can all be tested from the passenger window switch connector without having to take a lot of stuff apart. I have uploaded the wiring diagram for your window circuits. You can download a FREE copy at the following link: Window Circuit-01.gif

Just scroll down to the bottom of the page and select the link that says "slower download" , wait for the timer and enter the "captcha code" to download the file. Please note that you DO NOT have to purchase a "filesonic membership" to download the file. I have had problems with people thinking that I am trying to "sell" them a filesonic membership - this is simply NOT TRUE. The only thing I am selling is MY SERVICES and this is just one of the methods I use to deliver them.

When you check the circuits at the PASSENGER window switch, this is what you should find if the circuits are all working properly:

The BROWN/WHITE wire (pin 3) and the VIOLET/WHITE wire (pin 2) should both be GROUND with the driver's switch in the NEUTRAL position. The wire at pin 3 will switch to battery power when the driver's switch is in the UP position and the wire at pin 2 will switch to battery power when the driver's switch is in the DOWN position. If these conditions are not what you find, then the problem is either the driver's control switch or the wiring between the driver's switch and the passenger switch.

The BROWN wire (pin 8) and the VIOLET wire (pin 5) work similarly, however they are both grounded when BOTH switches are in the NEUTRAL position. These should toggle between power and grond when EITHER switch is operated. If the circuits above (pins 2 and 3) are working like they should, but these wires are not, then the problem is the PASSENGER switch. If ALL of these circuits are working as described, then the problem is the window lift motor.

Please study the wiring diagram so you can understand how this is all supposed to work.

If you need any further assistance, please respond back to this message to let me know.

Thank You for your patronage,

What would causw both electric front windows on 2005 caliver not to work? Already change out switches in the middle of the consel??

I would be willing to bet be willing to bet that you did not check for power and ground at the window switches before replacing them.
Please read this article before continuing: What Else Could Be Wrong?

I am assuming that you have the 4 door model since you specified "both" and "front". So this advice will be based on that. If you have the 2 door version, this could be very different.
If the rear windows are working and the front windows are not, that eliminates both the power source from the circuit breaker to the master switch and the ground circuit to the master switch, The only "component" that could cause both of these circuits to malfunction at the same time would be the master switch. You could, however, have separate failures of each of the window motor circuits between the master switch and the window motors. GM has had more than their fair share of window motor/regulator failures. This type of failure is not likely to occur on both sides at the same time. This would more likely work something like: Passenger side quits, then several weeks or months later, the driver's side quits. You could also have broken wires inside the umbilical between the body and the doors. With the older cars with the master switch in the driver's door, one broken wire could take out both doors. This does not apply to your vehicle, however. Again, this would also not be one of those things that would cause both sides to go out at the same time.
So to wrap it up, you need to check for power and ground moving into and out of the master switch at the correct locations and under the correct switch operating positions. This will require you to get your hands on the wiring diagrams for your power windows so you know what is what.
If the power and ground is ok at the master switch, then you need to remove your door panels and check for power and ground at the window motor connector. If you are missing either power or ground at any point, then you will need to do a wiring repair. If power and ground is available at the window motor connectors, then you need to replace your window motors and/or regulator assemblies.

2-door diagnosis is similar, but you cannot eliminate "source" power and ground to the master switch by operating the back windows. You will have to test for it at the master switch.

1997 Chevy Lumina, I replaced the passenger side power window motor due to the factory one failing, The person before me cut all the wires going to the motor and toggle switch in their attempts to fix /...

There is a wiring harness on hinge side of passenger door correct, take a look at the wiring colors. Hope you can read it. At the window switch, the outside wire on either side is voltage or ground depending on which direction, up or down, reversing motor. You don't need the window switch for testing, you should be able to operate from driver door master switch. If you get the wires reversed, the only thing that will happen is, up will be down and down will be up, if that happens, reverse the wires. Just my opinion.
At the window switch, top middle wire is lockout, so only the driver can operate the windows.

Looking for wiring diagram for 2001 Firebird power window. Driver side is down and won't go up. Passenger side works. I have power going to drivers side and not passenger side from the driver control...

You'll need to pull the door panel and check for power and ground at the 2 wire connector located near the window motor (there should be a dark blue wire and a brown wire). With a test light there should be power on one of the two wires at any time. If there is power on both wires with the switch in the up position than the switch is bad. If the only wire powered up in the up position is the dark blue wire than try tapping the motor while holding the switch in the up position. If it starts to work than the motor is bad.

On a side note check for power with all the connectors plugged in. You can also jump the connections at the motor. Supply a ground to the brown wire and supply power to the dark blue wire and the window should go up.

My driver side power window is stuck in the down position is there a way to get it closed? The toggle doesn't work but the rest of the toggles for locks pass window and power mirrors do

Remove the door panel,and the wire connector for the power window motor. Check to see if power is there when pressing the window switch. Check both wires, one for up and one for down. If power is present then its your window motor, if not your switch or power source. Good luck

Driver side power window shot

Sometimes on older models, the wiring between the door and the pillars is broken,

Pull the rubber cover over the wiring between the door and the pillar and inspect for broken wires. Even if you had power to the motor, when you close the door, there’s a possibility that the broken wire moves and losses connectivity

Let me know, Pierre ( Montreal )
