How to replace the multifunction turn signal switch on Buick LaCrosse?

When replacing the multifunction turn signal switch you should first turn off the restraints system and separate the upper and lower trims before marking the connector at the abrasion sleeve on the steering column wire harness assembly for restoration. Pull away the wire harness assembly from its mounting strap before taking off the turn signal and multifunction switch assembly wires from the restraints system. Separate the two connectors of the turn signal and multifunction switch assembly from the bulkhead connector and remove its two pan head screws to take out the assembly from the steering column tilt head assembly. Set the turn signal and multifunction switch assembly onto the steering column tilt head assembly with its electrical contact touching the turn signal cancel cam part. Secure the parts with both pan head tapping screws while tightening top screw to 3 Nm and side screw to 7 Nm. Push the two connectors into the connector body and join the turn signal and multifunction switch assembly wires with the restraints coil connections. Place back the abrasion sleeve onto the steering column wire harness unit while positioning the ignition lock wires and connector properly. Test the restraint system before inserting the cable assembly into its supportive structure while restoring the cover panels on top and below.

How to replace the Turn Signal Switch and multifunction hazard switch on Buick Regal?

Begin the switch replacement of turn signal, turn signal and hazard by first ending sir system operation then disconnecting the negative Battery Cable. Start by removing the Steering Wheel combined with the steering column trim covers while removing the wire harness straps that connect to the wire harness assembly on the column. Extract the Turn Signal Switch assembly connectors from the sir coil assembly connector and pull them out of the steering column bulkhead connector. Unfasten the Turn Signal Switch assembly screws then extract the assembly from the steering column. A small flat-blade tool should compress the electrical contact while you position the Turn Signal Switch assembly onto the steering column so it rests on the turn signal canceling cam. Use a 7 nm (62 inch lbs.) torque when installing the Turn Signal Switch assembly screws to the Turn Signal Switch assembly. Attach the Turn Signal Switch assembly connectors to the steering column bulkhead connector before linking both assemblies together through the sir coil connector. Reinstall the wire harness assembly to the steering column wire harness straps while verifying that the lever position remains in the center or off position before reinstalling the steering column trim covers and Steering Wheel on the steering column. Reconnect the negative battery terminal while enabling the sir system in the last step.
