How to service and repair the turn signal switch on Buick Regal?

You can start working on the Turn Signal Switch after setting the lever to its neutral off position and taking off the negative Battery Cable. Use the sir system off mode before taking out the Steering Wheel and steering column trim pieces. Release the wire harness straps from their position on the steering column and disconnect the multifunction, turn signal, and hazard switch assembly from its sir coil assembly interface. You can detach the multifunction switch from its steering column connector and slide it out of the bulkhead connector before taking off the screws that hold it in place with the tilt head assembly. Position the multifunction, turn signal and hazard switch assembly on the steering column by squeezing the electrical contact with a small flat tool while pressing the contact onto the turn signal canceling cam. Secure the multifunction, turn signal, and hazard switches at 7 nm (62 inch lbs) then join their connector to the steering column bulkhead and reconnect it to the sir coil assembly plug. Set the steering wire harness onto its connecting straps before placing the steering column trim panels and Steering Wheel when the lever remains in its center position. Reactivate the sir system before attaching the battery terminal again.

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.
