• Q: How to replace the Turn Signal Switch on 2005 Buick LeSabre?

  A: Disable the SIR system before replacing the turn signal switch. Keep the abrasion sleeve connector on the steering column wire harness ready by removing the parts above and below it. Disconnect the wire harness assembly from its strap to remove the turn signal and multifunction switch assembly socket from its connection with the SIR system coil. Move both electrical connectors of the turn signal and multifunction switch assembly from the bulkhead connection. Unscrew the two pan head tapping screws and disconnect the multi-function and turn signal assembly from the steering column tilt head. Place the turn signal and multifunction switch assembly onto the steering column tilt head assembly and make sure its electrical contact touches the turn signal cancel cam assembly. Secure the assembly with both pan head screws then start by tightening the top screw to 3 Nm (27 inch lbs.) and the side screw to 7 Nm (62 inch lbs.). Fit the two ends of Connector into Bulkhead Connector and link the Turn Signal and Multifunction Switch assembly connector to the SIR coil connector. Attach the abrasion sleeve to the steering column wire harness once more. Make sure the wires from the ignition lock cylinder case slot into place on their designated connectors. Put the wire harness assembly inside the wire harness strap while putting back the top and bottom trim panels and setting up SIR operation.
