We pull over, turn it off, turn it back on, and everything is working again. I disconnected the battery to maybe reset the computer but it has happened again. Not sure if it has to do with the PAC adapter or if it is coincidental and the BCM could be going bad? Crutchfield told me that was the proper adapter and the Axxess brand one isn't necessarily any better. Been reading it could be either things. Who knows... Think I'll pull the radio for a couple of days and see if we can replicate the issue we're having.
So we pulled the deck and the PAC RP5-GM11 for a few days and have not had an issue with the gauges going down. We've installed a GMOS-01 and have not had any issues with the gauges yet either. Might ask if Crutchfield will send us an Axxess ASWC-1 when I ask to return the PAC harness to them. Seems like something with the PAC was conflicting with the BCM and causing us the grief so not sure if the ASWC-1 will be any better. So far the GMOS-01 is working but sadly, no steering wheel controls.
