Windshield wipers stopping any place they choose.

[jakesz28]

Anyone know if I have to replace the whole wiper motor assembly or is there hope in fixing it?
This just started last night it was 34*f so not quite freezing. But on the slow intermittent setting it looks like they only wipe every other cycle. The cycle it does not wipe it only moves up about one inch. They will stay moving on the fastest setting but the next slower setting they go all the way up and stop. No wiping at all. When I turn them off they stop any where they choose.

Mine are doing almost the same thing. Typically try swapping out your windshield wiper motors first as I believe there's a nylon gear that has teeth that can strip out. If not that, next check your steering console selector switch, if not that, check the fuse box, and lastly, your BCM. I'd be willing to bet it's your windshield wiper motors.

Not sure if the Hs have them, but the older GMs had a electronic board by the motor. When the wipers stop next time you can tap the cover for the board. If they start working replace that board. If I remember correctly it's only a few screws and a single plug.
