Difficulty: Intermediate · About 120 min · Gmc Envoy

Replace the combination turn-signal switch on a 2002–2006 GMC Envoy XL after disconnecting the battery, moving the dash and column trim, and testing all switch functions before final reassembly.

Steps

1. Disconnect the battery and lower dash trim

   Switch the ignition off and disconnect the negative battery cable. Remove the lower dash fasteners and panels, then lower the steering column as needed to access the instrument trim.

2. Remove the instrument and column covers

   Release the tilt lever and remove the instrument-panel trim screws. Lift the trim away without losing its locating caps, then remove the Torx fasteners and separate the upper and lower steering-column covers.

3. Disconnect and remove the old switch

   Remove the column fastener with the E5 socket and move the upper cover aside. Unplug the combination-switch connectors, remove the switch retaining screws, and lift the assembly from its locating points.

4. Install and test the replacement switch

   Apply only a small amount of the specified lubricant to the mounting point, connect the wiring, and seat the new switch on its locating tab. Secure its screws, reconnect the battery temporarily, and verify turn signals and other switch functions.

5. Reinstall the column and dash panels

   Disconnect the battery again if needed while refitting trim. Reinstall the steering-column covers, instrument bezel, lower dash panels, and all fasteners, then reconnect the battery and perform a final check of the switch and warning lamps.

Check your vehicle’s repair manual for exact specifications and fit.
