How do you replace a 1994 suburban headlight switch?

Answer 1

Replacing the headlight switch in a 1994 Suburban is relatively easy but may take a little patience. It will required removal of the instrument cluster bezel.

Step 1: Disconnect the negative battery terminal.

Step 2: Remove the 4 screws at the corners of the dash bezel and carefully pull the bezel away from the dash. It still has wire connectors attached so just move it enough to be sure its free from the dash. If you have a tilt steering wheel it may be better to lower the steering wheel to its lowest position. Also set the emergency brake, take the gear selector out of Park and place it in Low.

Step 3: Carefully reach behind the bezel and disconnect the wire connectors from all the switches mounted in the bezel. Each switch has some type of clip keeping it connected to its switch so look at each one and determine how to release it.

Step 4: The bezel should be totally free from the vehicle at this point so carefully maneuver it out of the vehicle.

Step 5: Place the bezel on a flat surface with the backside up. Remove the 4 small screws that hold the switch retainer in place. Carefully spread the tabs on either side of the switch and push it out of the retainer.

Step 6: Insert the new switch into the retainer paying attention to the proper orientation of the switch and re-install the 4 screws.

Step 7: Reinstall the bezel by performing steps 1-4 in reverse order.
