Trying to fix things on the 2001 project Boxster I got. One thing I need to figure out is the central locking / alarm. I've searched and read every post in here on the issue and thought it could be an immobilizer issue. Pulled it while I had the seat out to recover it and didn't notice anything obvious, but I'm no expert. Basically the button on the center stack does nothing. Locking the door with the key only locks the drivers side (fixed bad key fob buttons but the car doesn't react to them). Never had any lights or horns chirps at all when locking / unlocking. Checked the C3 fuse and its fine.
Not sure if its related but a previous owner ran this wire from the window switches straight into the front of the fuse panel where there isn't a fuse. Removing the wire from the panel makes the windows inoperable. And this plug was in the bottom of the center stack connected to nothing.
