Whether you drive a convertible or a sport utility vehicle (SUV), some features come standard on vehicles across the board. One such feature is the dimmer switch. There are usually two dimmer switches installed in most vehicles, with different functionality. A function of one dimmer switch is to control the illumination of the instrument panels and dashboard lights --- adjusting your lights from a soft glow to high bright. A second dimmer switch allows control of your vehicle's headlights, switching between high beams, low beams and parking lights. You can replace your malfunctioning dimmer switch with a screwdriver and some patience.
Instructions
- 1
Turn off your vehicle and open the hood. Loosen the nut affixed to the negative (black) cable on your battery, using your pliers. This will disconnect the power from your battery and prevent a possible shock.
2Remove the trim panel from under the steering wheel. Use your flat-head screwdriver to carefully pry apart the trim from the mounted clips in the dash.
3Listen for a "snapping" sound as the trim unfastens from its position.
4Remove the cover panel, if necessary. Pull it off to expose the dimmer switch.
5Using your Phillips screwdriver, remove the screws from the mounted dimmer switch --- the small, black box with electrical wires.
6Pull the dimmer switch away from the mount to expose the wiring. At the rear of the switch you will see a plug containing the wiring. Remove the plug by pushing the plastic tab to release the plug from the switch.
7Discard the old dimmer switch; connect the new switch to the plug at the rear of the switch.
8Mount the new switch by inserting the screws into the mount. Tighten the screws with your Phillips screwdriver.
9Place the cover panel back to the original position over the dimmer switch. Affix the trim panel under the steering wheel, snapping the panel securely into place.
10Reconnect the negative cable to your battery and close the hood.
