Open & close driver window, passenger window, and service instrument cluster

[aquafalcon21]

Hey all! 2022 Tahoe LT with roughly 40k miles. I’ve seen someone post either or of this issue but never a combination of all three.

It started with open & close driver window. Did that twice a few days ago. Now it flashed service instrument cluster yesterday afternoon. Yesterday evening it said open & close passenger window.

Battery was checked and it’s good. No cables on battery seem loose. Any ideas? Dealership doesn’t have appointment until 2 weeks from now.

Thanks!

Going to have to wait for the dealer.

This sounds electrical…could be indicative of a bad ground. In order to figure it out, need to know the schematics and what might be in common between BCM and Instrument panel.
