Rear passenger door not getting power.

[shawn watson]

On my 02 A4, I am having a problem with my rear pass. door. First the window won't roll up or down. I also cannot move it up or down if I grab it with my hands and try to move it. So either the motor is bad, or it's not getting power. I suppose the regulator is fine, or else it would move up and down, when pressure was applied. Next is the door lock actuator is not locking or unlocking the door. It is either bad or not getting power also. All other doors locks work properly. Third, when I open this door, the interior lights have no response. No dash indicator either, It's like the car doesn't even know the door is open. I can lock the car, then open the door. The alarm doesn't go off, till the motion detectors get triggered. The speaker in this door is the only thing that is working. It works as normal, and has no problems. I looked at the conector where it goes into the door pillar. It is clan and looks to have no connection problems. I assume this is some kind of power supply problem, or the is some kind of controller in the door that has gone bad. Please, if you can point in the right direction for solving this problem. Also is there a good DIY for removing the door panel?

Thanks,
Shawn

Rear panel is very easy to remove. There is a module back there. Try unplugging it, cleaning it, and if all else fails, type the part number in www.genuinevwaudiparts.com and it should be a pretty cheap module. If you have a vagcom, you can find out if the module is bad for sure, my bet is on the rear door module. Each door has individual modules.

Well I don't have a VAG, this is my first Audi, and I'm still on the learning curve lol. Is the module in the door itself?

check the door boot for broken wires. same thing happened to me, only it was the drivers door so nothing worked. i pulled the harness out and there were four or five wires broken. soldered in some extensions and i was back in business.

I already checked that conection. All the wires look fine, as do the connections.

Wire could be broken inside that little boot.

I've already pulled that boot, checked the wires, and the connections. they are all good. Plus it would more than likely be several broken wires.
