problem details
2003 GMC Envoy 121,057 mi,
turn key on: only access ..nothing else. I can move gear shift, but no gauges and only "check engine" and "batt" light on. I took it to local Chevrolet Dealership...replaced ignition switch and it starts fine...but...the "Mechanic" triggered the "service 4WD, service airbag" and "seatbelt warning icon" ...asking me to return so the can FIX those things...I will not do that.
2004 GMC Envoy 166,000 mi,
