How to service and repair the headlamp dimmer switch on Buick Regal?

Service and repair of the headlamp Dimmer Switch starts with setting the lever to the middle off position while disconnecting the negative Battery Cable. Disabling the sir system enables removal of the Steering Wheel followed by the steering column trim covers. Remove the wire harness straps belonging to the steering column then separate the multifunction and turn signal and hazard switch assembly connector from the sir coil assembly connector. Remove the screws securing the multifunction, turn signal and hazard switch assembly from the steering column tilt head assembly to extract the assembly from the bulkhead connector. Additionally, detach the multifunction and turn signal and hazard switch connectors out of the bulkhead connector and extract the assembly. You should apply a small flat-blade tool against the electrical contact to position the multifunction, turn signal, and hazard switch assembly onto the steering column where the electrical contact rests on the turn signal canceling cam. Order the installation by screwing the assembly to 7 nm (62 inch lbs.) then connect the bulkhead connector to its assembly and finalize the connection with the sir coil assembly. The wire harness assembly needs to be reinstalled to the steering column wire harness straps before checking the lever position is center or off. Then add the Steering Wheel and steering column trim covers. The sir system becomes operational after enabling it along with negative Battery Cable reconnection.
