Pass side window/wiring problems
Pass side window/wiring problems Last night my pass side window worked fine. This morn I go to roll it down and nothing. I tried rolling it down with the button on the pass side and still nothing. I checked all fuses and still nothing so I figured the motor was bad, I pull the old one, while leaving it pulgged up but out of the car I try rolling it up or down and it will only go up but not down. I take the motor and get a brand new replacement and before I install it I try the same thing to make sure its going to work. Well once again all it will do is go up. I got my wire tester to see it it was getting juice to make it go down and I could touch it to the wire and press the botton down and it would light up. So im stumped. The drivers side buttons want control it all up or down. The pass side button will make it only go up. So im confused now. Its getting juice. Any one have an suggestions? on why it would go up and not down? And why the drivers side buttons want make it do anything?
Thanks!
Thanks!

Don't know but I have a similar problem. After replacing my passenger side motor (wouldn't move with either switch after doing the move a couple inches at a time thing for a month) it only works with the passenger side door switch - just bought a new module for the driver's side but haven't put it in yet.
Well I can hook the wire tester to the plug where the motor plugs in and press down on the drivers side button and it will light up, I can press it up and iit doensnt do anything. Is there some kind of lock out button or something somewhere? This is getting really irrating

I'm thinking the drivers side switch module has to be wired into the passenger side, right? I got no power at all to the passenger motor connector up or down from the drivers module so just bought a new one. Switch looked fine. Have you tried disconnecting the double window switch on the drivers side and see if it works with just using the passenger side switch? Something easy to try.

All control power for the passenger's window motor flows through the passenger's switch regardless of which side switch is actually pressed. So I would suspect a problem with the passenger side switch before anything else.
You can test the brown and dark blue wires between the right side switch and the motor. When UP is selected on either switch the dark blue will have power (12V+) and the brown will have ground. When DOWN is pressed on either switch it is reversed (power on brown and ground on dark blue).

Then why want the drivers side button make the windo go up or down, it doesnt do anything at all. The pass side button will only make it move up. Ive tested the wires and both are getting 12 volts when pressed up or down. The motor is brand new just got it earlier. The one I took out did the same exact thing, would only go up and not down. Any suggestions on what else to try or look for?

Verdad Gallardo Which one? Ive tested the pass side switch and it gets juice to both wires. The drivers side wire gets juice to all wires but the baby blue wire. You think the drivers side switch is bad?

Okay, it's not a question of whether you are getting power to the switch - it's a question of whether you're getting power from the switch to the motor. As I said before, test the output of the passenger switch on the dark blue or brown wire depending on which way you press the switch (either side switch will cause the same response). You need to have power on one wire and ground on the other when the switch is pressed. If you don't then the passenger side switch is probably the problem but there's additional testing you can do to confirm that. If you do then there is a problem either in the motor (unlikely since you've replaced it) or in the wiring between the switch and the motor.

On the drivers side switch the baby blue one is the only one that doesnt get power, I pulled the switch and it looks a lil melted on the bottom but nothing major looking. You think the driver side switch would be my problem?

Rather than guessing at what could be the problem, here is the wiring schematic so you can test various connections.

Iver ordered all new switches for both pass side and drivers side. Do you think the drivers side switch could be bad?

For example, if you suspect the left side switch then disconnect the plug at the right side switch and test there while operating the the left side passenger's switch. When the switch is DOWN you should have power on the tan wire and ground on the light blue wire. When the switch is UP you should get power on the light blue wire and ground on the tan wire. If you get the correct power and ground readings in those tests then the left side switch is working properly.
