How to Replace the Multi-Function Switch in a Chevy Avalanche

The Chevy Avalanche is known for its versatility and successful blend of passenger comfort and cargo flexibility. In addition to offering a full-size crew cab, it features the innovative fold-down mid-gate between the bed and the cab. The first generation of the Avalanche (2002 to 2006) offered a 5.3 V8 in the 1500 model and an 8.1L V8 in the 2500. Here's the details to replace the Multi-Function Switch in a Chevy Avalanche.
