Hi Guys,

I could really do with a hand in understanding how the electric window switches work in an 06 GP (3dr).
Basically my passenger window will only go down and not back up again. Now I've had the passenger switch all apart and from what I can see there are 6 connections:
- ground and live for the led light
- ground and live running from the battery to the switch
- two wires from the switch to the motor.

From my understanding the switch alternates the direction of the current running from the switch to the motor. I presumed originally that it must just be a faulty switch, so purchased a new one, however I'm still having the issue.

Also if someone would be able to give me an explanation into how the driver's side switch comes into the equation that would also be great, as I have no idea how that comes into the circuit.

Any suggestions and information would be greatly appreciated.
Many thanks,
Will
 
Here's the drawing, you're not exactly right, the passenger switch (H50) does NOT receive ALL the power from the battery, only the positive comes in directly; the earth (for the motor) comes from the driver's switch (H51).

When no motion is wanted, the switches are in the "neutral position" (vertical in the drawing), so pins 1 & 6 are grounded, pin 3 is @ +

If the passenger asks the window down, H5O will go like on the drawing so pin 2 will receive +, while pin 5 will still be grounded > motor runs CW (say)

If the passenger asks now to close the window, H50 will go to the right position so pin 5 now receives +, while pin 2 is grounded > motor runs CCW (say)

Same if the order comes from the driver's panel, pins 1 & 6 would alternately be positive or negative depending of driver's will.

Now what happens if BOTH switches are activated simultaneously in opposite direction ? >> Nothing, the motor would just be powered ++ or -- depending of motion combination > motor stop rotating.

Hope this helps a bit, regards, Bernie

Hi Bernie,
You have given an excellent explanation.

The circuit diagram is awesome.
Would you mind letting us know where you find such circuit diagrams?

All the best
Jack
