I'm new to this forum and I was looking for any post about central locking system and couldn't find one. If there is I didn't see it, sorry. But, here goes, I hit the button on my key and the only thing that happens, is the flashing of the light and nothing else. The door locks don't even move not even the trunk lock. Also the guide antennas that come up when you put the car in reverse don't come up. I was wondering do they all work together. I really need atleast a suggestion, on how to go about this problem or atleast how to start. I can open the manually sticking the key in the lock but only that lock comes up the rest don't.

Thanks,

The lock/unlock, lumbar, back up rods and vacuum headrests (rear) in addition to the back up vacuum for the HVAC are all controlled by the same pump under the rear passenger seat in a foam container. I think the trunk handle is also controlled by it on some models.
Try pulling the fuse and see if it resets, it has an ovepressure and runtime safety, but it also could be shot!
