How to replace the Turn Signal Switch on GMC Sierra 1500?

Disabling the SIR system requires specific safety steps before working on the turn signal switch. Take off the trim pieces from above and below before disconnecting the wire harness assembly from its strap. You should put back the abrasion sleeve on the wire harness assembly of the steering column and record where the connector goes for installation. Separate the SIR system coil connector from the two connectors (Turn Signal and Multifunction Switch Assembly) to release them from the bulkhead connector (Bulkhead Connector). Unfasten the two pan head tapping screws from the turn signal and multifunction switch assembly before taking it out of the steering column tilt head assembly. Set the turn signal and multifunction switch assembly onto the steering column tilt head assembly. Attach it with the two pan head tapping screws (Pan Head Tapping Screws) by tightening the top screw to 3 Nm (27 inch lbs.) for Domestic Column Shift or 7 Nm (62 inch lbs.) for Domestic Floor Shift and Export Column Shift while adjusting the side screw to 7 Nm (62 inch lbs.) for any configuration. The turn signal and multifunction switch assembly should maintain its electrical contact with the turn signal cancel cam assembly base. Put the connector ends of the Turn Signal and Multifunction Switch Assembly into the Bulkhead Connector and dock it to the SIR coil connector. Put the wire harness assembly back into the wire harness strap while lowering the connector and ignition cylinder case wires into the sleeve correctly. Put back the upper and lower trim parts then reactivate the SIR system.

How to replace the Turn Signal Switch on GMC Yukon?

Begin the turn signal switch replacement by disabling SIR then removing both trim covers. Disconnect the wire harness assembly from its wire harness strap. Also record where the connector sits in the sleeve for easy setup. Pull both Turn Signal and Multifunction Switch Assembly connectors away from their SIR system coil connection then remove them through the Bulkhead Connector. Disassemble the turn signal and multifunction switch assembly from the steering column tilt head by removing its two pan head tapping screws. Install the turn signal and multifunction switch assembly onto the steering column tilt head holder and fasten it using two pan head tapping screws. Start by screwing in the top screw to 3 Nm then tighten the side screw to 7 Nm. Push the assembly connector onto the SIR coil connector while aligning its electrical sensor against the turn signal cancel cam assembly. Insert the two connectors of the Turn Signal and Multifunction Switch Assembly into the Bulkhead Connector. Place the wire harness assembly into the wire harness strap with proper positioning of the abrasion sleeve around steering column wires that exit from the middle of the sleeve. Complete the setup by fitting back the upper and lower trim parts then make SIR operational.

Q: How to replace the Turn Signal Switch on GMC Sierra 1500?
A:
Disabling the SIR system requires specific safety steps before working on the turn signal switch. Take off the trim pieces from above and below before disconnecting the wire harness assembly from its strap. You should put back the abrasion sleeve on the wire harness assembly of the steering column and record where the connector goes for installation. Separate the SIR system coil connector from the two connectors (Turn Signal and Multifunction Switch Assembly) to release them from the bulkhead connector (Bulkhead Connector). Unfasten the two pan head tapping screws from the turn signal and multifunction switch assembly before taking it out of the steering column tilt head assembly. Set the turn signal and multifunction switch assembly onto the steering column tilt head assembly. Attach it with the two pan head tapping screws (Pan Head Tapping Screws) by tightening the top screw to 3 Nm (27 inch lbs.) for Domestic Column Shift or 7 Nm (62 inch lbs.) for Domestic Floor Shift and Export Column Shift while adjusting the side screw to 7 Nm (62 inch lbs.) for any configuration. The turn signal and multifunction switch assembly should maintain its electrical contact with the turn signal cancel cam assembly base. Put the connector ends of the Turn Signal and Multifunction Switch Assembly into the Bulkhead Connector and dock it to the SIR coil connector. Put the wire harness assembly back into the wire harness strap while lowering the connector and ignition cylinder case wires into the sleeve correctly. Put back the upper and lower trim parts then reactivate the SIR system.

Q: How to replace the Turn Signal Switch on GMC Yukon?
A:
Begin the turn signal switch replacement by disabling SIR then removing both trim covers. Disconnect the wire harness assembly from its wire harness strap. Also record where the connector sits in the sleeve for easy setup. Pull both Turn Signal and Multifunction Switch Assembly connectors away from their SIR system coil connection then remove them through the Bulkhead Connector. Disassemble the turn signal and multifunction switch assembly from the steering column tilt head by removing its two pan head tapping screws. Install the turn signal and multifunction switch assembly onto the steering column tilt head holder and fasten it using two pan head tapping screws. Start by screwing in the top screw to 3 Nm then tighten the side screw to 7 Nm. Push the assembly connector onto the SIR coil connector while aligning its electrical sensor against the turn signal cancel cam assembly. Insert the two connectors of the Turn Signal and Multifunction Switch Assembly into the Bulkhead Connector. Place the wire harness assembly into the wire harness strap with proper positioning of the abrasion sleeve around steering column wires that exit from the middle of the sleeve. Complete the setup by fitting back the upper and lower trim parts then make SIR operational.
