Rear wiper motor (revisited).

[Finless]

I have the wiper motor out and stripped down and everything seems to be in working order (now that it is cleaned). The circuit board seems to be un-burnt.

I can’t see why the rear wiper is not working.

Per the manual, there is only one fuse for the ‘wiper system’ and the front wipers work but not a twitch from the rear.

Does anybody know what setting to put a multimeter on to test the wiring. There are 4 wires coming into the wiper motor and 2 of them are noticeably thicker than the other two wires so I’m guessing they are the ones that carry the juice (brown and black w. Yellow stripe).

Have you checked the wiring from body to tailgate?

[Finless]

No. I am uncertain about my knowledge of how to use a multimeter so, at the moment, I am unable draw any definite conclusions (esp juice is arriving but nothing is working so it’s buggered).

Your best bet is probably to test continuity of wires across the body-boot lid with the continuity function (makes a beep when probes are connected) or simple ohm measurement on the multimeter. A sewing pin with a few strands of wire wrapped+taped around it then around probe to pierce the wire on the body side, then standard probe tip on connector at wiper plug.
