How to replace the Turn Signal Switch and multifunction switch on Chevrolet Express 2500?

You need to disable the SIR system before working on the turn signal and multifunction switch. Separate the upper and lower dashboard covers while remembering how the connector connects to the abrasion sleeve of the steering column wire harness. Take the wire harness assembly off its strap and disconnect the turn signal and multifunction switch connections from the coil connector of the SIR system. Extract both connectors of the turn signal and multifunction switch from the bulkhead connection point. Take the two pan head screws from the turn signal and multifunction switch assembly and remove the assembly from the steering column tilt head unit. Install the turn signal and multifunction switch assembly on the steering column tilt head by placing it down and matching the electrical contact to the turn signal cancel cam. Fasten the unit using the two pan head screws and ensure top screw at 3Nm and side screw at 7 Nm torque settings. Insert the two connectors into the bulkhead connector and join the turn signal and multifunction switch assembly connector to SIR coil connector. Put the steering column wire harness assembly back in place by securing it into the harness strap. Keep the ignition lock cylinder case wires and connector in their proper position while inserting the assembly. Put on the upper and lower trim pieces then make the SIR system active again.
