Hi, I'm Mike from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
In this video, we're going to show you how to replace the headlight switch on this 2003 Chevy Monte Carlo. The items you'll need includes a new headlight switch from 1AAuto.com, a 7mm socket, a ratchet, a T25 Torx bit, a flat blade screwdriver, and an E5 external Torx bit.
Underneath your steering wheel, you'll see this panel. You want to just push in these two tabs and pull it down. Then twist the socket free and pull the bulb out. Then you want to remove these two 7mm screws. Pull out your fuse panel door, especially make sure that the lower clip comes out. Then pull straight back on the lower panel on both sides. Then use a small flat blade screwdriver to help you release the clip on the harness to remove the harness.
Inside here is a T25 screw, just go ahead and remove that. Then pry out on this lever and it just pulls free, and then you can pull the panel straight down, unhook it, and pull it forward. Next, you want to remove these two E5 external Torx bolts. There's one right here and then one right here on the other side. We'll just fast-forward as Mike removes those. Once those are removed, you can pull this upper panel up and off. Now pull this panel off the rest of the way and remove this 7mm bolt right here. Pull down your glove box, and then remove this 7mm bolt right up here. Pry off this bezel. Then pull out on either side of the dash panel. You just want to feel for the clips back behind it and pull out. Once you get it free, just pull it forward.
Use a flat blade screwdriver to disconnect the hazard switch and be careful while doing this because you can break the bezel fairly easily. Now put your keys in the ignition, turn it to the on position, pull your shifter back all the way, and then lift your dash panel up and out. Now you want to remove these three 7mm bolts, and we'll fast-forward as Mike does that. Pull the switch out, and then pry out on the top and bottom tabs holding in the harness, and pull the harness free. There your switch is free.
On the left is our original part; on the right is the new part from 1A Auto. You can see there's a hole on the bezel, that's because the part from 1A Auto will fit cars with the fog lights as well. The switches are the same, and they mount exactly the same. Ours just has provisions if you have the fog lights.
Our vehicle is a little more rare and doesn't have fog lights, so we do the simple and inexpensive method of closing that hole out, which is just some black electrical tape. Put it on there, and unless somebody really knows your car, they're not going to notice that little repair. Reinstall the harness connection, put it back in place, and reinstall the three screws that hold in place.
To reinstall the dash panel, open up your glove box, turn the key to the on position, and pull the shifter all the way back. Pull your steering wheel down, and then tuck the dash panel back behind the steering wheel. Now reconnect your harness, and then you can slide your shifter forward and remove the key, and then push the dash panel back in the rest of the way. Then just push in the clips all the way around it. We'll fast-forward as Mike replaces those two 7mm bolts and tightens them up.
Just push this bezel back into place. Tilt the steering wheel back down and then feed this upper panel back into place and push it back down. Replace those two E5 inverted Torx bolts. Now, feed in the lower panel. You want to push the back back behind and re-clip those two hooks. Then swing up the front, push it into place, and then just replace that T25 Torx screw.
Reconnect the harness to your trunk switch. Then push this panel back up into place. Then replace those two 7mm bolts underneath the panel. Push the bulb back into the socket and twist it back into this panel. Then feed the panel back. Then push it back up into place.

My 2005 Monte Carlo SS interior lights did not come on at night. After scouring the electrical system I decided to change out the dimmer switch ( think the answer came from a monte carlo forum page?) Problem solved, all of the interior gauges and control lights work now.
