I had replaced the motor, wiper arm with a used unit and noticed the intermittent function did not work ( had installed the assembly as I had received it, so I also replaced the multifunction relay with a new unit.

No CHANGE in the intermittent function, the hazards and rear window defrost are fine (had problem with rear defroster before so that was cured)

Still also having problem with the park position of the wiper - cannot seem to figure out how to align it on the motor shaft so it works properly.

One ex Mercedes master mechanic said that it is controlled by the motor itself- I think he may be wrong.

I prefer not to be changing the motor again


Any help/suggestions would be welcome.

To find the correct park position for your wiper,first park the motor by turning the wiper off at the control stalk,remove the complete assembly, then slacken the nut which holds the crank onto the motor shaft(you will have to free the taper with a sharp hammer tap on the nut), move the drive head to the park position(there are index marks on the back of the drive head under the rubber seal) then retighten the motor crank nut while keeping everything in position ; the motor crank and drive link should be parallel to each other.
Refit using just the bottom nuts to check operation , then if ok refit properly , lubricate all the sliding mechanism under the turtle shell and job done.
Don't know about your problem with intermittent wipe, but if you have fitted a new relay I think the fault must be in the stalk switch.
