1999 Primire electrical issues

[AJ&J]

HI I have a1999 Olds Silhouette with a few electrical gremlins. It started with the slider working intermittently then not at all. Weeks later the Traction control switch did not toggle the indicators (in dash or on the switch) but the system sometimes did disengage.
A short time later the rear wiper lost function, however the rear washer still works.
Lastly (at least to my knowledge) last week the drivers window would not roll up,
The passenger works fine. I back probed the switch assembly and found proper voltage out .I removed the door panel and with jumper wires rolled up the window. I was able to again roll it down with the switch, however not back up with the switch only the jumpers.

Thank you,
AJ

Power Sliding Door - I'm not sure how the power sliding door knows where it is, but I believe there are 6 or 8 electrical contacts that connect when the door is closed (they may have nothing to do with it knowing where the door is, but I don't know why it would be designed that way if they didn't.)
If they are corroded it might confuse the system. Also there is a reset/relearn procedure for it you can find if you do a search.

Rear Wiper - Mine doesn't work either, but check for voltage at the wiper motor. If you have power, then the motor is bad. Otherwise check for voltage before and after the switch and so on.

Traction Control Switch - No offense, but are you absolutely sure it does disengage sometimes? Can you spin the tires on gravel. Also, if one of your wheel speed sensors is acting up then your traction control wouldn't be working. I don't remember what the traction control switch did on our van before I replaced the hub/bearing assemblies.

Drivers Window - If you have the proper voltage out of the switch, then it has to be a broken wire or bad (corroded or loose) connection. I believe windows roll up and down by reversing the polarity. They have two wires for the motor - to roll down wire A is pos and B is neg; to roll up wire A is neg and B is pos, so be sure to check both wires.

I hope some of this is helpful. I don't know much about these systems, so if I am wrong someone please speak up.

clean the plates and switches that stick out of the side doors with some fine emry cloth to get them shiny .the reset or re-learn for the power side door is to get it all the way to the rear of the track. the window switches get corosion build up on the contacts and if they can't make contact then that part doesn't work.as for the tcs it could be a wheel sensor ,the pass-thru connector in the floor board behind the driver's seat corroded or loose wire on the tcs that is in front of the gas tank underneath the van.
