man this is getting better!

been d%@$ing around with these windows for days now.

1. the driverside rear window works intermittently, front pass. works all the time- rules out fuse
2. jumped the motor to the battery it works
3. went to pick up the regulator arm and it breaks in my hand- fixed that
4 hooked motor up before the switch- no go
5 seems to be intermittent power just at this window

I am new at this.

any shared experience would be appreciated.

i think i have a bad wire. Is there an efficient way to locate a short without pulling all of the carpet up and following the wire? Once the wire enters the cabin it goes to the front fuse box in the inside of the car right?

God grant me the serenity....

Every problem that I have had with anything electrical in the drivers door has been due to a wire breaking at the hinge point between the door and the frame. I found that if you take the panel off the door and find what ever wire you need and cut it inside the door then solder on new wire at both ends of the cut then remove the side kick panel in the foot area you can then pull the wire through and cut out the bad section and resolder that end of the new wire. I have fixed my seat, window and door locks by doing this.
The drivers door of course gets opened far more that any other so the wires break there long before thay do to any other door. My drivers door window started doing what yours is doing and thats how I got onto this problem and repair.

i have been reading some of your previous posts with regards to door window issues. i was unable to find one that fit my issue. i will give it a try.

you as well as so many others that share their time here are valued and appreciated.

Also clean all the terminal, both male and female at the switches. Then take the switches themselves apart and clean them up inside. This has solved many a mysterious electrical problem for me..

I'm slightly confused...#4 hooked up motor before the switch.
Are you talking about the switch on the door, or on the console?

I understand there is only one window switch, on the console. Many problems are connected to "dirty" switch connections. Try cleaning them. Or replacing switch. Hope this helps.

i would think that just before the switch on the door there should be "live elect. current" this is where i spliced into to see if it was live by hooking the motor up to this area, after cleaning the contacts. it had worked by doing this in previous tests-intermittently.

i dont think it is the switch i have consistently tried both switches (console/door) and they either both work or neither. unless it is possible if one doesnt work the other doesnt as well? i would hope this is not the case in its design

disclaimer- newbies beware: this is unchartered territory for me

bad ground

is it ok to just splice in a wire to the existing ground wire and ground it to a screw?- i hope so.

the power window seems to be on all the time, does this suggest new window button or can it be cleaned out, or something else?

Assuming the 126 window circuit is the same as the 123, check the drivers window switch/connections, as it is the master and has the lockout button. Good luck

My car has the same type issue, but on the rear driverside door. The switch at the console does not feed power to the window motor, but the switch on the door operates the motor just fine. Both rear windows need the regulators looked at as they shutter going up or down insread of operating smoothly like the front windows.

With the switch in "neutral" power is provided to both terminals of the window motor. When the switch is actuated, the power to one side of the motor is interrupted and that circuit is grounded.

Power to the rear door switch is provided through the console switch. There is no way for the door switch to work if there is no power at the console switch.

Well, I cannot lower or raise the left rear window from the console, but I can from the door switch. The window lock on the console does work.
