Here are the items you'll need for this repair: 7-8mm sockets, ratchet, extensions, flat blade, and a Phillips head screwdriver.

Remove the three 7 millimeter bolts along the top side of your dash bezel with a socket and ratchet. Remove the two 7 millimeter screws on the center trim bezel below the radio. We use a small flat-blade screwdriver, with some tape on it to keep from marring our dash services, to pry out on this center trim panel. Reach back and disconnect all of the electrical connectors. The antenna pops right back and out. This last connector for the four-wheel drive selector is going to have to be pried up on with our flat-blade screwdriver. Remove this 7 millimeter bolt that was covered by our center dash panel.

Remove the four 7 millimeter bolts: one here, two below the hood release, and one all the way by our left foot, using a 7-millimeter socket and ratchet. Slide the knee pan forward toward you to release the hooks and remove it from the vehicle. Remove this 7 millimeter bolt through the access hole in this steel reinforcement behind the knee pan. Remove these three 8 millimeter bolts using a socket and ratchet. Pull back the knee panel. We'll remove this last 7 millimeter bolt.

Now we're going to put our column all the way down, if you have a tilt option. Put the key in, and shift the vehicle to first gear to get a little more room around the stick. Pull out on the dash, and lift up.

Using a flat blade screwdriver, remove this electrical connector for the interior dimmer switch. Push down on the tab. Release the other connector from the headlight switch.

To remove the interior light dimmer switch, I'm going to flip our panel over and remove these two screws. Remove the dimmer switch from the dash.

Install the dimmer switch with your two Phillips head screws. Now our dash panel is ready to go back into the truck.

We'll shift our truck down into first gear again, so we can lay our dash panel back in. When you get pretty close to getting it lined up, take a second to reconnect the electrical connectors for both the headlight switch and the interior dimmer switch. Lay the upper dash panel back into place and you'll see the metal clips and their holes. Line them up, snap them back in.

Shift the truck back into park. Remove your key. Reinstall the gold 7 millimeter screw at the top right corner of that upper dash panel. Reinstall the three black 7 millimeter screws into the top of the dash panel just before the instrument cluster. Reconnect the four-wheel drive selector connector. Reconnect the cigarette lighter. There's two wires there. Reconnect the radio harness, the antenna, the fog light switch, and the AC power outlet connector. Push the center panel back into place. Then reinstall the two 7 millimeter screws at the bottom of the panel. Reinstall two 7 millimeter screws at the bottom of the upper dash panel. Reinstall the three screws for the steel knee pan. Tighten them up with an 8 millimeter socket and ratchet.

Snap in the top of the plastic knee pan. Reinstall the four 7 millimeter screws along the bottom. Remember to reinstall the hood release and the two screws that go in there.
