Major power failure in numerous systems 2008 Chevy Tahoe Z71
So I just bought my 08 Tahoe and all of the sudden
all the following things stopped working...
Read folding seats
DVD video player
The guy I bought it from just had the windshield
wiper interval relay replaced. Could that have
shorted something out? Please help!
Do you have a check engine light? It sounds like the BCM has lost communication with the accessory inputs. If that is the case then the dealer will have to reflash the system to match the VIN. Your lucky, a lot of times when this happens the engine won't run due to a lock out in the anti-theft system that is programmed in the BCM.
Yes but wiper interval relay is up under dash under dash smaller than your phone. There are many harnesses under there for Body control module like tennis shoes said either needs to be reflashed or simple plug detatched
