98 E36 M3 Alarm Door Lock Problem
I just traded my 5 series in for a 98 E36 M3 sedan last week. I bought it off my mechanic who was selling it for one of his customers. There is a problem with the door locks when arming the system through the remotes. When pressing the arm or disarm button I get 4 or 5 chirps and the doors dont lock. From my research, this means that the car thinks there is a door that is not closed. Could this be a faulty door switch? I can use the key to lock and unlock but both alarm transmitters wont lock the doors and arm the system. Is there any way to test to find out which door it thinks is not closed? Any help would be great, thanks!
