2016 Freightliner M2 Wiper Control

[RV Lou]

Hello,
Just obtained this coach, really like it so far. Going through and fixing all the broken stuff. The W/S wipers only run on high, no intermittent or low. They do not auto return to the parked position at the bottom. I have cleaned the connector coming out the stalk, the PO had a new stalk switch which I installed and no change. Is there a control module somewhere possibly? Seems everything these days has one.

TIA,

I don't have a Seneca, but I did find a wiring diagram for wipers here on page 5. I hope this helps narrow it down for you.

Thanks, that should help diagnose the problem.

Here is the electrical diagram for the M2 Seneca... if the forum will allow it to be posted.

Thanks Steve! That is a tremendously useful file, will come in handy for some other issues I'm having I hope.

Thanks again.
