I have a "95 e420 and the drivers side seat does not go forward and
short out fuses. I am able to move the seat back but not forward. I
when I try to move the seat forward I heard a clicking noise. I am not
sure if the problem is with the seat switch, the forward motor,  the
seat control unit, or the wiring connecting to the seat motor.

Again the seat moves backward, not forward and shorts out fuses and
makes a clicking noise when trying to move forward (before shorting out
the fuse). Passenger seat works fine.

Any diagnostic ideas appreciated.

Thanks,
Jim
