Ok my car's got an aftermarket alarm on and wired direct to the alarm module for the c/l (underneath the steering wheel column an its negative multi-point so the faster locks) when its cold when I disarm the alarm the locks fail to open or if I lock it, it fails to open. But even if I'm sat in the car and I lock and unlock the door, nothing happens, as I'm driving sometimes I can hear a clunk from the o/s rear door. Getting worse now as the nights get colder, is this a problem with the motor or the module itself?
