Here's my current modules. The 2 in the pic together do nothing and are faulty. The one on the pic on it's own is the odd mismatched opposite side mix up one.

My pass switch up puts the drivers window down, pass switch down puts the drivers door window up. My drivers switch up puts the passengers window up, drivers switch down puts the passengers door window down.

I'll check this out later when I get home. I suppose this might be possible. At the time I bought the motor, the only way I could get one with that part number after a lot of searching back then was on ebay via a european parts seller

Hi Pete I definitely need your help. I have 2 faulty motor units or else one faulty car. Maybe you know the fault already. The passenger switch in the drivers door operates my drivers window and the drivers window switch operates the passenger window but the switch is back to front so up is down and down is up. Any ideas? I suspect it might be a wiring fault but i'm not sure. I'm going to be stripping parts off this week to check connectors etc so any pointers would be good. I have 2 motor units with the same part number.

@Wino Your colours appear to match what I have in the door. I want to go through each pin and check it out with a multimeter. It may be the weekend before I get a chance to do that though. I'm particularly interested in finding out if the earth connections are solid and reliable as dead earth lines can reverse signals in certain circuits. We see this sometimes in tail lights in cars where the earth is dead and the wrong bulb starts flashing. French cars are prime candidates for this. My plan is to basically wire direct lines to each pin to where it should be connected elsewhere in the car to see if i can identify any suspect parts of the loom. Because the fabia door cards are riveted it rules out me doing a proper test mid loom within the door without having to rebuild it.

I'll hopefully get to check these pin numbers and colours out this evening to compare.

I took the wiring diagram from a 9n3 polo to get the pin outs of the 2 connectors that go into the top of the window motor. I'm not sure it'll help much but worth having it here for reference. If someone has elsawin for skoda to cross reference it would be good but i'm pretty sure the pins should be the same. T6aa - 6 pin connector 1 - ro/ws - front left window switch (pin 4) 2 - sw/bl - LIN bus 3 - ro/gn - rear left door switch pin 4 - not used 4 - ro/bl - rear right door switch pin 2 - not used 5 - li/gr - rear window reg isolator switch - not used 6 - nc t8h - 8 pin connector 1 - br - earth on A pillar 2 - ro/ge - fuse 31 25A 3 - li/ws - LIN bus 4 - br/ge - drivers side lock module pin 8 5 - bl/ws - drivers side lock module pin 4 6 - br - earth in door loom 7 - ro/ge - front right window switch (pin 2) 8 - bl/ge - drivers side lock module pin 4

Relay tested and working perfectly fine. Back to the drawing board. There's a QR code on one of the chips which i scanned and it just came up with the number 00421478 so probably some number relevant to Temic who make these boards.

So here's the relay. I'll have a look at the circuit and see if i can test it. It would be great if it was as simple as a faulty relay https://uk.farnell.com/panasonic-electric-works/act512/relay-automotive-spdt-14vdc-20a/dp/2292929

Yes both second hand. The relay is on the motor side of the circuit so it would be switched by the controller and send power to the motor terminals.

Checked out the board under magnification. Nothing obvious wrong, no cracks, scorches or burned components. One large relay on the board. My initial thoughts are to test it but it's been a while since I worked with relays and without knowing how it's wired i'll need to do some research to fin out how it's operated. I'm going to put a few volts to the brushes and just make sure the motor fires up first.

I'll go and get the one that stopped and open it up.

And I know it appears to be a lhd vs rhd type of problem but I have seen this same problem appear on another couple of posts out of the blue with the original motor so I'm not sure if there's some way to do a reset of everything or if there's a problem elsewhere.

So despite the main part number being the same they can be LHD and RHD? Is it possible to rewire the switches? I have a spare switch unit. I wouldn't mind doing this if it got me by for a bit.
