This video addresses the bad Chevy Colorado / GMC Canyon 1st gen under hood grounds and the problems caused by them. My truck has had issues with the blower motor, door locks, fuel gauge, and anti theft due to these. The problems seem to become more noticeable on hot day or on long drives where the under hood heat is the worst.
