Re: Electrical Nightmare
If your window motor is constantly clicking with the key out (mine was), it could be contributing to your battery drain. It sounds as if you have a bigger problem than just the electric windows, but this is what I did to fix mine. Hope it helps.
First, I proved the passenger side motor was ok (the stuck open window) by connecting 12v and earth (operating voltages according to the manual) to the 2 terminals on the motor using a battery charger and insulated probes from my avo meter. Tricky but I got there. Swap the connections round and the window goes in the other direction so I managed to close the window.
I then tried doing the same with the drivers side motor (the one getting hot and clicking). It clicked but would not move. I then removed the motor and opening mechanism completely by removing about 5 bolts in the door and 2 into the door glass (get someone to hold the door glass while you are doing this if you can). The motor can then be separated from the mechanism by removing 3 screws. The motor itself is sealed but I sprayed WD40 down the shaft and got it turning a lot easier. On the end of the shaft there is a metal worm screw (I think that's what it's called) which fits into the opening mechanism and drives a nylon cog. The grease on the screw and cog was contaminated with water. I cleaned this up as much as possible and put some fresh grease in. Reassembled in reverse order and both windows work, for now anyway. I don't know but I'm guessing the control unit could not operate the good passenger side motor because it was too busy trying to do something with the drivers side.
Just a thought, it might be possible to separate the motor from the opening mechanism without removing it from the door. As long as you you can get at the 3 screws, have enough room to manoever and can see round corners.
Good luck Bradnock.
