Can anyone help me?
The passenger electric window stopped working about 6 weeks ago, after cleaning the switch it was as good as new.
Then it started to work intermittent. Now it has stopped altogether. I have swapped the working switch but still not working??
Any help would be appreciated.

One of the places I might check is the cable connection at the hinge point of the passenger door. These are prone to corrosion and cause all sorts of unusual faults in the doors. If you've tried a known good switch but still nothing then I'd rule that out. Did you try the switch you cleaned up in the driver's side to ensure it was working?
Does the switch illuminate when ready to operate?

Yes both switches work on the drivers side and both light up but do not operate?

Yeah it sounds like something between the switch and the window mech has decided it doesn't want to play anymore. I guess the only other test is to apply 12 V to the window motor and see if it moves. But it sounds more like an electrical contact fault somewhere.

There isn't really anything else between the switch and the motor but cable and a couple of connectors.
