Really, really weird passenger side window switch issue

Really, really weird passenger side window switch issue

Postby Kirkus [OP] » September 1st 2011, 5:55am

Okay everyone, hold on to your hats because this is a weird one!!!!

My driver's side master window switch broke a few months ago. Naturally, I replaced it with a new one. The day I replaced it, the passenger side switch stopped working. So, I figured that it was the new switch. I put the old switch back on to see if the passenger side switch would work again. It didn't help at all. So, I decided to go and buy a new passenger side switch. I connected the switch and I got nothing. After the switch didn't work, I remembered that I had broken wires in the door boot. So, I fixed the wires and the window moves faster now but the switch still doesn't work.

Now, here's the crazy part...I have current coming to all of the wires on the switch. EVERYTHING HAS POWER but the new passenger side switch and old passenger side switch do not work at all. The only way I can control the window is from the driver's side master switch. Has anyone experienced this or have any suggestions???

Thanks in advance!

Here's the schematic for my 89 if that helps -

Note that all switches are grounded in their resting state. So if you try and
test the window motor by applying 12v to the two terminals, DISCONNECT the
switches from the motor first, otherwise you will be causing a direct short
from 12vdc+ to ground.

Tell,
__us exactly which wires that have power.

Be sure to double check fuses, relays, & any thermal fuses you may have.
Then check for any shorts in the wiring from the Drivers-side onto the Pass-side.
Some choose to shift.
While others, choose not to.

Check your ground.

When you tested your wires for current, did you put the other lead into the connector or did you ground it on a piece of metal (such as the door)

Secondly, test the switch with a meter or continuity tester. Based on that you said so far, I don't think that it's the switch but you never know what you can find out from that.

Thanks for the replies guys! I had to put the problem on the back burner for now. From what I can remember, I'm pretty sure I used the latch post on the body or I used the passenger seat stud as a ground. I am not sure as of now but I think I was getting a positive light from all of the wires in the window harness that connect to the back of the switch. I honestly cannot remember if this is correct though. All my fuses are good, for sure. I didn't think to check and see if one side of my relay was bad. I might need to do that. Again when I tested the wires in the harness, I grounded my test light and checked the wire connectors for current just as I normally would.

Thanks again for all the help. You all's input is very helpful!
