GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hello, my name is***** you tell me if all of these issues started at different times?
Thank you. The gauges are a common failure on this vehicle. This is caused by a failure in the stepper motors in the gauge cluster. The cluster would need to be rebuilt. As for the check engine light and the ABS lights the computers would need to be scanned for codes. Most auto parts stores can scan the computer for codes for free and give them to you. If you can bring me the codes it may shed some light on what is going on. It may be a vacuum leak in the intake manifold gasket.
