Ok so I installed a keyless entry system with the proper relays in my 1991 Mercedes 300E. Everything was working fine for a couple of hours, and I was extremely happy. I think I got a little to trigger happy with the remote when the problem happened. The locks would not open with the remote OR the drivers door pin. Neither locked/unlocked the car. However, the passenger's door pin still unlocked/locked the doors. So I yank out the back seat to get to the vacuum pump. I notice that the drivers door is only sending 6 volts to the connector when unlocked (used to be, and should be 12v), and still sending ground when unlocked.

I disconnected the relays, and hooked up all the wires like they came from the factory, yet i still have the problem. The Driver's door will only send 6v. At one point, the drivers door started sending 12v while unlocked, but 4 volts!?!?!?! when locked. I am so confused.

Any help would be appreciated.

THANKS!

EDIT: Allready checked fuses
