3 speed wiper help please! (wiper Guru needed)

Do islands function to open and close contacts?
I asked first, lol.

Figure out a way to test continuity or measure contact voltage.
Done. See post #1. Park switch is good.

Verify motor body has ground with meter.
See post #1. Done. Grounds are good.

Momentarily jumper park contact as test, to see if motor runs.
Yep. I've done the stand alone test. Same scenario. Motor runs. Won't park.

Which is why I'm asking about the islands and their function and if mine look good.

Thanks for the reply!!! I'm gonna know about 3 speed wiper motor functions before this is over.
I'm just like that. I've got a spare to play with on the bench.
