I have a strange problem with the electrics on my passenger door of my A4 B7 Cab.
I removed both front door cards to fit puddle light looms, no problems with fitting them following info from this site.
The problems started when we tried to code them in, VCDS could,nt communicate with them, though in retrospect "I think" this maybe correct as my friends S4 B7 Cab is exactly the same. Time was short so we put everything back together and the puddle lights worked ok on the drivers door, but nothing on the passenger door at all and now the electric window now doesn't work from the switch on that door.
I thought that I might have either forgotten to plug the door card loom back in or maybe the switch, but I took off the card again this weekend, and everything is as it should be.
The passenger window operates ok from the drivers door switches, I checked for a possible blown fuse and fuse 22 is intact, (drivers and passenger door 15A), the drivers window works perfectly as does the electric mirrors on both doors and the central locking as well, now looking at the motor it appears there is a door control unit but it is part of the electric window motor, and there seems to be three plugs going to this unit. I have even swapped the door switch units over with my mates S4 Cab, and mine is good, so I,m at a loss now.
The only thing I can think of is the control unit on the motor has gone U/S, or possibly a damaged cable in the door hinge area, though as the window can be operated from the drivers side and everything else seems to be ok in that door I,m inclined to think that the cables are ok.
Has anyone got any ideas? its a bit baffling to be honest.
