Default 80 series rear wiper issue

Calling electrical gurus.

Rear wiper operates on intermittent even when switch is turned off.

I checked the switch and didn't have continuity between pins 1,2,10, and 16 when switch was off.

So is it the relay or the wiper motor? Or should I check the switch again?

See attached pdf...

The relay side of the L-R wire is getting 12V when the wiper motor is disconnected. I think it's supposed to be 0? So if that's true that points to the relay.

Pins 1 and 4 of the wiper motor have continuity, about 20 ohms resistance. I think they are not supposed to have continuity at rest, so if that's true that points to the wiper motor.

Or maybe I'm reading something wrong?
