Tools required

Parts

• Turn signal/multifunction switch assembly × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and set parking brake
2. Turn ignition to OFF position and remove key
3. Disconnect negative battery cable and wait minimum 2 minutes for airbag system capacitor discharge
4. Adjust steering column to lowest tilt and telescope position for better access
5. Mark or photograph wire connector orientations before removal for easier reinstallation

Procedure

1. 1

   Remove lower steering column cover
   Locate the two Torx T20 screws at the bottom of the lower steering column cover. Remove both screws, then carefully pull the lower cover away from the column, disengaging the retaining clips. Set aside the cover and screws.

2. 2

   Remove upper steering column cover
   With the lower cover removed, locate the Torx T20 screws securing the upper steering column cover. Remove these screws, then lift the upper cover up and over the steering shaft. Note the alignment tabs and clips for reassembly.

3. 3

   Locate turn signal switch assembly
   Identify the turn signal/multifunction switch on the left side of the steering column. The switch includes the turn signal lever and is mounted to the steering column with two mounting screws. Identify all electrical connectors attached to the switch body.
4. 4

   Disconnect electrical connectors
   Locate the electrical connector(s) on the switch assembly. Press the locking tab on each connector while pulling straight out to disconnect. There are typically 2-3 connectors depending on options (turn signal, wiper, cruise control). Use masking tape to label each connector position if needed.
   ⚠Do not pull on wires; only pull on connector bodies to avoid damaging wire terminals.
5. 5

   Remove switch mounting screws
   Using the Torx T20 driver, remove the two screws securing the turn signal switch assembly to the steering column mounting bracket. Support the switch assembly as you remove the second screw to prevent it from falling.

6. 6

   Remove turn signal switch assembly
   Carefully slide the turn signal switch assembly off the steering column. Guide the turn signal lever through the opening and remove the complete assembly. Inspect the mounting location on the steering column for any debris or damage.
7. 7

   Install new turn signal switch
   Position the new turn signal switch assembly onto the steering column, aligning the mounting holes with the bracket. Guide the turn signal lever through the proper opening. Ensure the switch sits flush against the column mounting surface before installing screws.
   ℹ️Verify the clockspring connector orientation aligns properly before seating the switch assembly.
8. 8

   Install and torque switch mounting screws
   Install both mounting screws by hand, ensuring they thread properly without cross-threading. Once both screws are started, torque each screw to specification using a torque wrench. Alternate between screws to ensure even seating.

9. 9

   Reconnect electrical connectors
   Reconnect all electrical connectors to the turn signal switch assembly, ensuring each connector clicks into place and the locking tabs engage fully. Verify each connection by gently tugging on the connector body. Route wiring to match original configuration.
   ⚠Ensure connectors are fully seated; partial connections will cause malfunction or error codes.
10. 10

    Reinstall upper steering column cover
    Position the upper steering column cover over the steering shaft, aligning it with the lower mounting surface. Ensure all alignment tabs and clips are properly engaged. Install the mounting screws and torque to specification.

    Reconnect battery and initialize system
    Reconnect the negative battery cable. Turn the ignition to ON position without starting the engine. Observe the instrument cluster for any warning lights related to the turn signal system. Check that no airbag warning lights remain illuminated after system initialization.

Reassembly

1. Ensure all steering column cover screws are torqued to specification to prevent rattles
2. Verify steering column covers are fully seated with no gaps
3. Confirm turn signal lever operates smoothly through full range of motion
4. Check that all electrical connectors are fully locked and secured

Verification

• Turn ignition to ON position and verify instrument cluster turn signal indicators flash when lever is operated in both left and right positions
• Test hazard light function by pressing hazard switch; all four turn signals should flash
• Verify windshield wiper controls function properly (if integrated with multifunction switch)
• Test cruise control functions if equipped and integrated with the switch assembly
• Confirm high beam and flash-to-pass functions operate correctly
• Check that turn signal lever returns to center position after completing a turn
• Verify no warning lights remain illuminated on instrument cluster
• Test drive vehicle to confirm turn signals automatically cancel after turning and all functions work under normal driving conditions
