Doors won't lock, lights don't turn off

[bmischle]

Hi all!

I am currently having an issue with my doors not locking and the interior lights staying on. When I attempt to lock the doors with either the fob or in the door, the doors sound like they attempt to lock but don't, and the car beeps twice. The lock button on the dash does nothing, no light. I found that if I turn the key in the door and hold it, the driver door will lock but not the passenger door. If I turn the key 3 times, the driver door locks, the horn beeps once, but the passenger door still does not lock. I have replaced both door mechanisms, gas cap has a new lock, oddments compartment securely shut, new ignition switch, and I even replaced the lock button on the dash. I also had the central lock module checked by a Porsche specialist, and they said everything looks fine, no water damage. I'm am not sure what else I can check, without spending hundreds on the Durametric scanner or taking to a dealer. Any new ideas are greatly appreciated. Thanks everyone!
