GMC Troubleshooting Questions? Ask a Mechanic for Answers
Welcome, I'm Chris (aka Moose), my normal schedule online is around lunch and after dinner past midnight.
While chiming only while moving that is likely the parking brake partially set or the parking brake switch not working right.
No instrument cluster indicators working is going to mean the instrument cluster is faulty. The warning lights get inputs from many places so each input can not be bad.
Thanks for using Just Answer, and rating me so I am compensated, Chris
