    One window doesn't open by remote

    Hi there. I've got problem with my Astra H 1.6 2006 GTC. One window doesn't open by remote. Passenger's window works just fine - open and close by pressing open/lock buttons on remote. Beside of this malfunction, driver's window works great. I can open\close it by door switch and even close it using remote. I've already checked wiring loom and door's connector - no broken wiring. Can someone provide me guide what to check next ? Or connector pinouts description so i could check if there is correct voltage at all of them ?

      Does the 1 touch down work on passenger side?

      You mean that if i push and release button then window would go down independently ? Yes it would. I checked today errors in REC module and got "B3803-00 - faulty operation of comfort closing windows circuit". But i can't reproduce that error after erase...

      Door connector pin 9.
      There is brown/Black wire.
      It is comfort closing signal for window.

      Thank you for your reply. I just found that pin at the wiring diagram and checked it. There is continuity between door plug and REC module. And between door plug and the fuses too. I will check wiring inside door next...

      I checked wiring inside the door and it's ok. So there are 2 things left: REC and window motor. But its weird... What do you think ?

      Do you get any voltage to this pin when you push lock button continually ?

      So here is the deal... At the brown/black wire there is constant +12V. When i try to open windows by remote then voltage drops to ~5,8 V. When i close both windows by remote then voltage drops to ~0 V. Both windows wirings behaves the same so i think wires are ok... I think that window's motor is guilty. But im not sure because i still don't know how this thing works. How could motor rotate both ways if there is only 1 powering wire (for comfort closing\opening) and only thing that changes is voltage, not polarity of current :/ ?

      If you remove connector from driver's window motor does the voltages stay the same when you commands windows with remote?
      Or have you measure that without this connector loose?
