GMC Acadia is a crossover SUV produced by General Motors under the GMC brand since December 2006. Built on the GM Lambda platform, it replaced the Envoy mid-size SUV in the model lineup. Below is a detailed technical reference for the fuse box diagrams and electrical distribution centers for the first-generation GMC Acadia (Lambda platform; chassis code GMT968) production years 2006–2012.
This guide provides locations, diagrams, and circuit assignments for the power distribution boxes. Fuse locations responsible for the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
