Power Window Switch schematic
I was attempting to help a fellow Pelican with a power window problem and in the process attempted to figure out how those nasty little switches worked. Armed with a Fluke meter I came up with the following:

Thank You for the wiring diagrams
Everything looks the same, except driver side passenger window switch 1.=red/blk. 2.=red/white once I switch those two wires like your diagram where 1.= red/white 2.= red/blk. the passenger windows stops working. If I live it 1.=red/blk. 2.=red/white the passenger works either way I switch the wires the driver/passenger switch does not work I tried another switch in excellent condition and still did not work any other ideas? Thank You |
You can rule out a power issue because the passenger door switch works. That indicates that there is 12 volts on the driver's door Passenger switch.
I think you have a bad ground connection on the switch that is not working. Attach a wire to terminal 4 and clip it to the metal door frame and see if it works. The next guess is the switch is bad. If the internal sliding contacts aren't moving then the switch never provides a ground. If you want to experiment swap switches. It might just make more sense to install a new one. |
I got a switch from a local porsche shop (parts heaven) and attched it still did NOT work.
Your right I am starting to suspect a bad ground Thank You |
jtkkz - Did this turn out to be a bad ground? If so, how did you fix it?
My scenario; Driver side switch - works fine Driver side passenger switch - does not work up or down Passenger switch - works fine I have checked all three switch connections numerous times and I can't get the driver side passenger switch to work. |
I never got it to worked, I gave on it for now....
I tried all the different wiring combo, nothing worked. It use to work fine till I removed it to replace my door panel... I have the exact same scenario as you... Driver side switch - works fine Driver side passenger switch - does not work up or down Passenger switch - works fine |
It's a conspiracy!!! I am going out to the garage in a minute to troubleshoot the same thing. I will let you know what I find.

Seems pretty simple
On the drivers side door switch With the switch off there should be 12 volts (battery voltage) between pins
With the switch up (maybe down the schematic isn't clear) there should be 12 volts between 1 and 2 and -12 volts with the switch in the other direction (zero neutral position). |
The beauty of these switches are that they can be disassembled and cleaned. I've repaired mine that way, saved a lot of time and a few bucks, too.

just a JW quote just in case
"JW says, looking at the back of the switch, with the single terminal at the top, the red wire goes to the top and bottom right, the brown ground goes bottom left, and the two other wires from the motor go on the middle two. if the motor goes the wrong way, swap the middle ones. the right window won't work if the left window switch is bad, or wired wrong" |
I had no time to trouble shoot this issue this weekend, but the switch decided to work intermittently today... I think the door panel needs to come of at this point so I can check out the wiring. I have tried moving the switches around. It's not the switch.

Hi...My first post.
This is REALLY helpful. ...I have printed this out to help me in my project. I have think I have incorrectly wired and maybe bad switch(s) as well. But this is just what I needed. |
how about a diagram for this pesky power mirrors.
|
:D
Both windows now work !!! I had power where needed but finally tracked things down to a bad Pass switch and a bad ground on the Drivers side. GREAT info Thanks. OK ... now for more projects |
Here's my issue:
Passenger window goes DOWN via Driver and Passenger switch, but not UP from either. Its at 4" open right now, starting my trouble shooting run once the kids are settled. Thinking straight for the door panel, I have power/ground to go DOWN but not UP.... Thanks! |
Great diagram, very helpful - I am in a passenger side RAISE-ONLY fail situation...tracing the loops in this diagram helps me isolate where to look for my problem ("1" to ground "4", passenger side switch).
Off to the door panel! -Todd |
new switch open circuit
I just spent the weekend cleaning and greasing my passenger window mechanism. Everything worked fine except the new switch. It turned out that the internal connection, in these diagrams from 4 - X was open. Check it with an Ohm meter otherwise your window will only travel up or down.

3 New "German" Switches Installed, Solved My Problem
Quote:
The finish of the new switches to be completely different than the stock, even the size is a bit bigger, and the color more grayish and matte so I'm glad I got all 3 so they at least match each other. (Are the Porsche official ones black and shiny?) BUT after a quick ground check of the switches themselves (thank you 5495bb) they plugged right in and all the windows are now working great. SO I have 1 good stock switch, and 2 questionable samples if anyone is interested in doing rebuilds of these nasties... -Todd |
Power Window use relay?
Power window needs relay? It seems difficult to make use of relays in these scheme? I am connecting my windows from scratch, and I am afraid to run the power directly thrue the switches. How big fuse does I need for the power window? 30A?

Thanks for the diagram. I just have had two what I thought were unrelated situations finally seem to come together.
Three times in the last month I have come out to a dead battery. The battery charges fine and holds a charge. I have checked to see if I left lights on, those parking lights with the turn signal ---nothing. Then I noted that the passenger window switch on the drivers door had a broken spring and sometimes would stay in the "UP" position. Now my passenger window is not working from either switch. Fortunately it is up. My question is this: Could I have burned out my motor by having the switch stuck UP or is there a cutoff once the window is in the up position? If there is no cutoff, this could explain the erratic discharging of the battery. Is there an easy way to check to motor? |
