Just purchased a 2003 CLK500 and the locking/unlocking feature using the Smart Key doesn't work. Did some investigation and found that Fuse #8 keeps blowing, which tells me there's a dead short someplace in the circuit. Ironically, Fuse #8 is part of 3 circuits, i.e., Anti-theft alarm, Convenience locking, Remote Boot Trunk release. All other fuses associated with these circuits are fine.

Does anyone have availability of a wiring diagram that I can use to trace the circuit.

Found the problem. It was the Alarm Horn mounted in the passenger side well. Unplugged the horn, car not locks/unlocks from Smart Key.
