What did you do to your NNBS GMT900 Tahoe/Yukon Today?

That's not the OEM part #. The AC Delco OEM part number is 1741152. That part is the step below OEM and it's a couple bucks more than Rock Auto before the 5% discount so therefore I'd stick with the Rock Auto part but that's just me

On the way to work today my windshield wipers quit. Doesnt matter what I do, the wipers don’t move. I turned key off, opened door, turned key on, nothing. Also unplugged the rain sensor, didn’t help. Manually activating them doesn’t change anything. I still have turn signals, washer fluid spray, high beams, just no wiper activity. Had to drive the rest of the way to work without wipers. Glad I took back roads and not the interstate this morning. Any ideas of what I could check before I leave tonight?

bust out the tech2 and see if it will command them on, if not then probably the wiper control board

i'm reading over the service manual, there talking about replacing a fuse block or the bcm if the wipers won't go, ugh hopefully you just blew a fuse

Welp. I checked the fuse before leaving work, it was still good. Currently at the dealership on the way home. Got here 90 min before close so they were able to get it in for diag. Will see what they come up with
