I recently replaced the front passenger side window regulator (just the track, not the whole panel) and re-inserted the little round plastic thingys in the rear passenger window so it could go up and down.
Now, the central locking seems to think something is not right. When I engage it, it immediately sets off the alarm. Same thing trying to use the key to lock it. When I'm in the vehicle, I can lock all doors with the driver side switch. I can't even lock it from the outside by pushing down the driver door lock - it goes a little way, but won't lock. I disconnected the battery for 20 minutes, which worked on other locking issues in the past, but did nothing this time.
