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

To fix the Turn Signal Switch you first need to remove the battery's negative cable and steer wheel. First you need to take out the tilt lever and steering column shrouds before moving on to the left closeout panel. Twist the two torx(R) bolts off the multifunction switch while disconnecting its electrical ends and the switch falls out. To install the multifunction switch you first put it back into position and fasten it with the two torx(R) bolts while turning them to 7 nm (62 inch lbs.). Pass the electrical wires through the space and connect all electrical components. Replace the steering column covers and install the left panel on top. Repace the Steering Wheel and tilt lever before activating the sir system.

How to replace the Turn Signal Switch on Buick LaCrosse?

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.

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.
