Re: Does anyone have good wiring diagrams for the wiper motors?

Just to start with, what's happening inside that park switch? My logic says there's no power going through it; only ground. Based on the diagrams, one wire gets spliced over to the slow speed motor ground. The other wire goes back to the column switch.

Your description of the operation made the most sense. Both p.78 and p.79 make no sense in their portrayal of the column switch.
I was posting that from memory and I screwed up.
You are correct the park switch is grounded from the OFF switch position. I'll edit my post to correct that.
The power wires run to the motor and the motor mounted washer.
