W209 wipers inop, changed motor, relay, bonnet sensor, stalk but still nothing.

[Rex Egerton Chesney]

My W209 wipers don't work, but the washers do.


Replaced -
Stalk
Relays
Bonnet sensor
Wiper motor and linkage
Fuse


What else could it be? Faulty SAM?


Many thanks

What about a diagnostics check for fault codes buddy ?

I had it plugged into Star and they suggested it was motor related as the relays etc had power to them. But replacement good motor and nothing.

Have you checked the voltages to the components and continuity.
