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.

Remove the Multi-Function Switch

  • Remove both cables from the battery, then wait 10 minutes to allow the air bag system to disable. Pull out the tilt wheel level on the steering wheel to disable it. Make sure the multi-function switch is OFF.

  • Take off the knee bolster and remove the screws from the lower column cover. Title the cover down and then slide it back to disengage the locking tabs. Remove the head screws from the upper column cover.

  • Lift out the steering column lock set and the upper cover. Disconnect the wiring harness straps that lead to the steering column wiring harness.

  • Disengage the Brake Transmission Shift Interlock (BTSI). Locate the gray and black connectors from the bulkhead connector and unplug them. Remove the switch screws and take out the switch.

Install the Multi-Function Switch

  • Set the new switch in place. Compress the electrical contact with a small screwdriver blade and secure the switch into position. Make sure the electrical contact is resting on the canceling cam assembly.

  • Put the screws in place to secure the switch. Torque the screws to 53 inch lbs.

  • Install the upper column cover. Fasten the bracket nuts and tighten them to 22 foot/pounds. Put the knee bolster in place as well as the steering column cylinder lock. Tighten the screws on the column cover to 12 foot/pounds.

  • Place the lower column cover back in position. Tighten the screws to 53 inch/pounds.

  • Check to make sure that the switch is in the OFF position, then install the steering wheel. Reconnect the cables to the battery. Enable the air bag system.
