1996 Electric windows stopped working on both doors.

[bboles01]

I had the passenger side window start to work sometimes and not others then about a month later it just stopped. Driver side was fine but then it started doing the same thing. I checked fuse and no issues there. Any clues??

Have to check the switch with a test light, see if there is power coming in somewhere, Start with the driver's door switch.

If you have power coming in, then hold the switch and see if there is power coming out. If not, bad switch.

Next would have to pull the door panel and check for power at the motor (if the switch has power passing through it)

There are rollers inside the motor that are meant to shear under high loads. They deteriorate over time, that could be the cause of your problem.

I had the passenger side window start to work sometimes and not others then about a month later it just stopped. Driver side was fine but then it started doing the same thing. I checked fuse and no issues there. Any clues??

The motors have gone bad so here's the deal if you change one change all back window included

 

[goodO1boydws]

It sounds like a weak connection-one that finally got too bad to complete the circuit. f its not a switch, Maybe a rusty or oxidized ground connection point or inside of a connector. I'd try using a battery and light gauge jumper wires across the questionable motors-using the motor wires at the closest connector, and if the motor works, work that way, go back to the next connector, or switch, until I got to the fuse panel.

Coincidentally, my next door neighbor called me YESTERDAY about a window motor in his Mom's Geo that he said was bad. He said it had been acting up and finally stopped working. (With the window glass all the way down of course.) He wanted help/advice to get the window glass out-which is seldom necessary. (Even on a Geo.) He had the motor/slider assembly loose inside the door and even had the correct junkyard part to replace the "bad" motor/cable/slider assembly. But he couldn't break loose the screws holding the vertical guide part of the slider to the glass. And withthe slider guide it was too thick to pull it out the top of the door-as he'd found out.

I asked him how he knew the motor was bad. "It doesn't work-when I use the door switch or the master switch nothing happens-not even a clunk."
Did you test the motor? No
Well, since he had the replacement junkyard part handy I said let's try this one first to make sure it works. Using similar gauge wire to the car wiring, i used jumper wires, and the motor wouldn't do anything. The jumper wire quickly got hot, and started smoking though. Figuring that maybe the aslider was at the end of its travel and was trying to move against the stop I reversed the wires, same thing. Well he did get it from a JUNK yard-how can he complain?

Did the same thing with the unbolted original motor-it worked fine.
He's now trying to find the connection that's bad-i don't old out great hopes he'll find it. BUT I try to rember that sometimes the simplest things are missed and I've been as guilty of that myself as anyone fromk time to time.
At least the window is closed now-and its been raining a lot here lately.

Here's the power supply diagram for power windows



Here are the power windows system diagrams




If any door locks work, it's not a power supply.

If no door lock action, but power tailgate works, you might have a break at splice S502.

(Location S502 Window regulator left front door harness, near T/O to C500)

Translation:
Splice 502 is a 3 wire, light blue w/ black splice inside driver door that is found in harness close to window motor connector C500.

Your best testing is going to be right at driver switch with a test light. (Or power probe if you have one)
