In this video, we're going to be working with our 2006 Chrysler 300. We're going to show you how to remove and replace your HVAC control panel or your heat and AC control panel. These control where the heat or AC comes out of your vents as well as the speed and how hot or cold the air coming out is. If you like this video, please click subscribe. We have a ton more information on this vehicle as well as many other makes and models and if you ever need parts for your car you can follow the link down in the description over to Here are the items you'll need for this repair.

In order to access some of these parts, we'll have to remove this dash panel here. Fortunately, with this trim removal tool, available from we can get this plastic piece out without worrying about damaging any of the other interior pieces. All you've got to do is get behind it, and pry out. There's clips all the way along the side, so just keep moving up little by little, prying it out. Now we can slide this forward and access the electrical connectors at the back. All you’ve got to do is push down and release the tabs. Over here has got one of those red safeties which, actually, is another great use for this tool. Just pop that little tab out and release the connector. We'll move on to these ones up here. You have you ESP and hazard switch as well as the little electrical connection for the clock.

To remove your HVAC control panel flip the bezel over and on the backside there are four 4 millimeter screws. I like to lay the bezel down flat since I already have it out. That way I can remove the screws nice and carefully. You want to be very careful not to drop those because they're very small and they can get into some tight places and you might not find them again. Remove the HVAC control panel from the dash.

Reinstall the HVAC controls by laying them back into the dash panel. Again, I like to lay this nice and flat. You want to make sure that it's not up on your leg. Otherwise it's going to hold those switches out. Just start those screws in, nice and careful.

Once you've tightened up all of the four millimeter screws we can reinstall the dash panel into the vehicle. Now, it's a little bit easier to connect the bottom first. We'll start by reconnection the HVAC. All these connectors are different sizes. You can't really mix them up. Don't forget the little red clip that goes in the big connector here. Just slide that in, lock it into place and that keeps it from falling out. Reconnect the ESP and hazard switch at the top center and the light switch all the way at the top for our clock. Set the panel back into the dash. Just press around the edges until everything sits into place and everything is where it should be.

To reset your clock, it's very simple. Right now it's three o'clock even. Holding the button will get the clock to move. You can let on and off because it'll speed up as you hold it longer. Just a couple of taps and it's three o'clock.
