Some brilliant diagnostic work here guys, well done. I don't have much to contribute - I measured the same resistances in the switch as you did Wino, but as I mentioned elsewhere I have resorted to rewiring the system to power the motor directly without the motor controller PCB. I have kept it undamaged so I can return to the problem one day, but for now I have working windows (drivers side so far, passenger hopefully this weekend) so am happy.

You both obviously have much greater commitment to understanding and properly solving the problem than I do! Well done. If I find anything interesting when I take the passenger side door apart I will report back.

Thanks

Just came across something interesting and hopefully relevant to the motor rotation direction in a youtube video about window motors.

 

Check out what he does and says at about the 17 minute mark here: Electric window motor bench test, strip & fix #1423 - YouTube  

 

Rather than having swapped the rotors between passenger and drivers side, you may have put both motor covers on the opposite way to how they were?   I will bench test this at home later. Thinking about it, it must be the relative orientations of brushpack and cover that matter, and I can't remember whether or not the brushpack can fit into the cover either way round. Wish I had one in front of me now.

Hi Wino

 

Top of the class for you brother.

 

I don't have much time and will post over the weekend. I have just taken the drivers side window motor off and I had indeed put the motor on 

so you could not see the label when the door card is off . I have turned this through 180 degrees so you can now see it. Put it all back together

and it works the way it should. ( Push the switch down window goes down Pull the switch up window goes up.)

How ever the left door window is still working back wards off both the drivers door switch and passenger switch.

Took the passenger door card off and I had also fitted this motor so you could not see the label. Turned it through 180 degrees so you can now see the label

put back together and this is also working the way it should from both the drivers and passenger door switches. ( push down window goes down pull up window goes up )

Just wanted to let you know.

Well done mate.

No pictures at the moment will try and sort something out for next post.
