So i Own a 1999 Audi A4 1.8t Quattro Manual Trans i dont know if its early or late i have conflicting parts so idk. BUT the problem right now is that the passenger window when given power and i mean when ever the motors pluged in and the battery is conneted it will continusly spin in the direction rolling down the widow it worked intill i was driving one day and i tryed rolling it up and they where trying to roll it down(by accedent) and i have swithced buttons and unlplugged both bottons and swap in used units from other cars and the problem persists. I know theres a computer that interprets everything in the car Could that be the issue? I also noticed after these test the drivers window wont one touch down anymore after i unplugged the battery a couple times through out my testing. Any help would be appriciated.

 

The motor might have a short circuit and it constantly receives the command to roll the window down. Go to a good electrician, it should be a very simple problem.

 

Have you tried swapping the drivers control for all of the windows? Doesnt really sound characteristic of the central locking module, if all of the windows were rolling up or down then maybe...

 

yes i have

 

Either a Relay or Switch is stuck.

 

whenever you disconnect the battery,you have to hold both the driver and passenger side window buttons up for 10 seconds,then the one touch up and down will be programmed.

 

turns out after testing the motor the small circuit board within the motor itself fried and jump constang power and down.
