If you need to fix your window right away then try this. Open the driver's side door about half way. Hold the window switch in the Down position. Firmly close the door while still holding the window switch in the Down position. Window should go down. This is only a temporary fix. I believe you will need a new window motor soon. Also the same trick works if your window gets stuck down. Just hold the window switch in the Up position while firmly closing the door.

This has worked for me for the past several years. My window has been stuck about 7-8 times now and this trick aways works. No new window motor yet. Recently my father's Chevy Suburban passenger side window stopped working. I was able to get it working again with the same trick. It's been two months now and he hasn't had a problem with it. Another happy customer.

Sorry to hear that. One thing to note is that some people close the door harder than others. It would be more accurate to say "slam the door" than "firmly close the door". Doesn't work on my car unless I slam the door. You have to close the door hard enough to jostle (move) a contact point within the motor.

Another thing you may want to try is removing the window switch panel from the door and take it apart to clean the contacts in the switches. All you should need is a small flat tip screwdriver. The whole panel comes apart and there are metal contacts in each switch that tend to get corroded with black charcoal like dirt. Clean them really well and put it back together. You can use either electrical contact cleaner or some emery cloth to clean them. This has worked in my 97 deville and the problem is solved.

Simply test your switches with an OHM meter or a CONTINUITY tester, you will need to remove the switch module to do so.

Oh good. I will have a look to see if the rear motors have a common ground point in my manual. It is odd that 3 motors would be out, Ill check the wiring diagram later tonight. I am going to the Jersey shore and will need to look through the manual tonight

Alex, I looked through the window schematics. It appears to me that if you have power at the switches, the motor is at fault. Many circuits are grounded to S402 namely, the rear defroster, power antenna, sunroof, windows, etc. Furthermore, each rear motor has its own ground wire back to S402. S402 is located on the floor of the trunk RH front, 17 cm from the P400 breakout. As you know RH (right hand) and LH (left hand) is determined from the drivers seat perspective.

Have you tried to operate the rear windows from the rear switches? There is a lock out for the rear windows to keep the kids from playing with them (which I use too). Did you try the door banging trick with the rear doors?

I would think that if you took the door covers off, and tested for power at the motor connector when you pushed the buttons you would confirm that you either have a motor problem. Did you happen to notice if the LIGHTS DIM when you push any of the buttons, indicating that the window regulator is jammed?

I don't have a scanner here, but if you need the schematics, I can send them at some point. Be careful fooling around with these window motors and regulators with your hands in there, you can be badly injured if the window suddenly moves and catches you... stay clear, let me know if I can help.

If you need parts, I will do my best to help you out if you don't have access to parts on your side of the pond.. Let me know how I can help, Mike

Funny!

Even if Alex is a good sport, I'm not certain he'll

enjoy that!

Thank you WarrenJ for youre files, so this afternoon i took out my window motor, i tested it with 12 volt and it work fine, i open the window motor and i clean the rotor it was very dirty, i put the window motor in the door and it workkkkkkkkk yeah yeah yeah, i am very very happy, i would like to thank bodyfisher it is a very nice man, and the other member of the forum, but i have yet one little problem, when i turn on the a/c or the ventilation, there are a few smoke who are coming out, but not every time. The smoke have no odors, and the night i have many condensation of the driver side, the smoke coming when the ventilation is in low position, it is not real smoke it seems like a fog...what do you think.....

YEAH!, I am glad you figured it out good for YOU!

Our AC experts will chime in on your AC issue, the fact that it does not have a smell is interesing. No mildew, electronics, no coolant smell?, just condensation? Pull your rug up and see if its damp. When the AC is running check to see if condensate is coming out of the HVAC housing from the hose... I hope its not freon.

Again, if you need anything that I can help you with, send me an email here. Mike

Where you have "it was disconnected", that is the LOW SIDE Thermister, see this photo #1

1996_AC_System.jpg

The other connector, I am not sure of, I will look at my car in the morning I don't have a flashlight here, its dark. Is your car running ok?, there are at least 2 connections that go to the ignition module, check to see if they are connected? I don't think your car would run if the connectors to the ignition module were disconnected. That might be for something like the HEATED WINDSHIELD or something like that.. Ill have a look, Mike

Have you checked for codes, that low side thermister should have set a DTC code, I assume that export cars have the ability to check codes

A thermister measures temperature, it is the low side temperature sensor.

Here is a description from the manual

The low side temp sensor is located in the low pressure refrigerant line between the orifice tube and the evaporator. The ACM monitors this sensor to determine the low side pressure based on the pressure temperature relationships of R134A.

if the low side thermistor is disconnected... it may be letting the evaporator be getting too cold.

It may be just extra cold air coming out... cold fog.

Like when you open a freezer door on your refrigerator and the cold air from the freezor hits the warm air from the room.

If I am not mistaken....(KHE where are you :D ) the low side thermistor and the high side thermistor, measure the temperature of the freon and send the info to the computer to cycle the AC compressor on and off as needed.

If the compressor is NOT cycling on and off... the evaporator will get colder than normal and will cause the fog that you are seeing. Especially on low speed (which would be low air flow) or when you push the ECONOMY button. That lets warm moist air blow across the very cold evaporator and could cause the fog.

I could also be totally wrong... I work on computers and networks for a living. :D:D

Alex, great job on the driver's door ...

did you check to see if the rear door window's lockout switch was activated ...

did you check for power at rear windows switches ???

i have owned alot of old cars and it is very unusual for the rear motors to be

worn out ... the most used motor is almost alway the drivers window and i use to swap

the motor for right rear window for the drivers... that is the window that i least care about useing ...

bon chance

hmm maybe an OBDI will allow the compressor to stay engaged if there is a sensor fault?, very odd, I am going to disconnect mine tomorrow and see if my compressor stays engaged.. I would be very surprised if it did.

"Fog" from the dashboard vents indicates moisture is being retained in the heater box. Most often it is a sign of a leaking heater core. That, of course, would result in a distinct antifreeze odor and a deposit of coolant on the windshield. Also a damp carpet at the front passenger side.

Since you don't notice that odor/deposit I'd guess it might simply be pure water that is causing your problem. It might be that the drain on your heater box is clogged.

Do you notice a steady stream of water droplets hitting the ground just behind the passenger side front wheel when the A/C is on? If not, your drain tube might be plugged.

Regards,

Warren
