Intermittent rear wiper problem 08 Yukon

[Doubeleive]

this is why a tech2 would be great, you could simply command the rear wiper on and that would rule in or out a bunch of troubleshooting

also I don't see any notes on the rear hatch glass/arm position so far, on my nbs if the rear wiper wasn't seen as parked the rear glass would not pop open, may not be related at all but I remember them being related to each other on the nbs

I had a problem with mine, googled it, and was told to check the ground from the motor to the hatch door. I put a toothed lock washer on and it fixed it. Maybe completely unrelated and I have a GMT800, but just thought I'd throw that in mix.

Also double check the nut/wiper connection, my wiper was cracked(Where it bolts on) and did the same thing, it would wipe and stop(I presume the shaft and nut were spinning) A new wiper arm/blade fixed it.
