2003 GMC Yukon SLT 8 Cyl 4.80L
Body & Interior
What am I missing? Fuel Gauge broken.
I've got a 2003 GMC Yukon that was hotwired a while back. I've fixed the wiring since but a handful of things stopped working after. Windshield wipers won't turn on, High Beams won't turn on, Traction Control won't turn off, and the Fuel Gauge is no longer functioning. All the fuses are double checked and triple checked functional.
Check the relays (as applicable), and then trace the wiring to each non-working component, using a detailed electrical schematic.
