• Q: How to replace the Turn Signal Switch on 2008 Buick LaCrosse?

  A: Before you replace the Turn Signal Switch you need to deactivate SIR system mode. Remove all the trim pieces from the top and bottom part of the steering column then install the driver side harness sleeve back onto its housing while documenting the connector location for reassembly. Pull the wire harness assembly out of its strap before taking off the turn signal and switch assembly connector from its connection with the SIR system coil. Pull the two connectors from your turn signal and switch assembly so they leave the bulkhead connection. Pull the turn signal and switch assembly from the steering column tilt head assembly by removing its two pan head tapping screws. Fit the turn signal and switch assembly onto the steering column tilt head assembly and let the electrical contact rest on top of the turn signal cancel cam assembly. Secure the assembly by turning the two pan head tapping screws until they reach 1 N.m (9 lb in). Insert the two connectors into the bulkhead connector followed by connecting the turn signal and switch assembly to the SIR coil connector. Place the abrasion sleeve back on the steering column wire harness assembly while placing the ignition lock cylinder case wires and connector correctly. Insert the wire harness assembly into its holding strap before replacing both trim panels and turning on the SIR system.
