In this video, I’m showing some basic repairs on a 2003–2007 Classic Chevy/GMC/Cadillac GMT800 instrument cluster. This includes bench testing the cluster with IPC Hammer, doing a gauge sweep test, identifying burnt-out backlight bulbs, replacing cluster bulbs, removing and reinstalling stepper motors, and explaining the common dim or blank display issue caused by bad solder joints/resistors.
This applies to many GMT800 vehicles, including the Chevy Silverado, Tahoe, Suburban, GMC Sierra, Yukon, and Cadillac Escalade from the 2003–2007 Classic body style years.
