W204 C200 (2011) Estate Rear Windshield Wiper Inoperative
Hi,
The rear windshield wiper stopped working a while back. The washer still works, but the wiper doesn't move. The indicator for the rear wiper lights up on the dash, as normal. I found the fuse and checked it (13). I'd like to check the relay, but I'm not sure which one it is (I posted another thread about that). I stripped down the tailgate and took the motor off. It runs if you apply current directly to the connector on the motor. With the motor remounted, I'm measuring current only on the middle pin on the connector. This is intermittent, which I assume is fine as it's an intermittent wipe. If you use the wash function, it shows continuous current while the wash function is operated. No current at any time on the other two connection pins. We tried a new motor and that was the same.
Any thoughts would be appreciated.
