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.
