How-To: Change HVAC Panel Light Color

How-To: Change the color of your HVAC panel


If youíre considering doing a total LED conversion, you may want to START here. This will give you an idea of what is involved with the other process, and is MUCH EASIER than the instrumentation.

Tools Needed:
  • 7mm socket and wrench, or a screwdriver with a socket adapter
  • Flat head screw driver

Remove the two 7mm bolts above the A/C control *****. It is easier if you pull off the control ***** first, but is not necessary.

Remove the radio bezel by getting your fingers between it and the dash and pulling straight out. There are 2 clips on each side which hold the top portion on, so you may want to work from one direction to the other (bottom to top works well).

It is highly recommended you disconnect everything attached to this bezel and set it aside
The connections should consist of:
~Aux 12V power supply (two pull-off connections, one female spade and one rubber-type)
~Cigarette lighter (one pull-off polarized connection)
~Antenna (pull-out male connection)
~Radio harness (a flat head will help in removing this harness)
You may have more switches for fog lights or 4x4 switches, but since I donít, I canít describe the connection type. Someone please PM me the type of connection (pull-off harness, spade connectors, etc.)

Now remove the four 7mm bolts around the outer edges of the A/C panel. This isnít necessary and wonít allow you to pull it too far out from the dash because of the vacuum hoses connected to the back, but youíll be able to accomplish the next task much easier.

Using a flat-head screwdriver, pry up on the black plastic where it clips onto the white plastic:

Now youíll be able to remove the 161 bulbs and replace them with the LEDís. However, I was cheap and didnít want to buy more LEDs so I removed the green plastic wedge-base adapter by twisting it out and bent the prongs of the 194 bulbs to contact the metal electrical-contacts on the reverse side of the white plastic panel.


Before putting this all back together, you'll have to seperate the two layers of the HVAC panel face. It's glued on, but remains adhesive after you pull it off so you won't have to re-glue it:

In this last picture you can see the two sockets for the lights, one with a 194 LED and one with the green plastic wedge-base adapter. As mentioned, you can buy 161 LEDs that simply plug in to replace the stock bulb, but I'm cheap so I retrofitted and soldered. I can still de-solder it and replace the wedge adapters if I get some 161 LEDS too.

Reverse the steps to put it all back together and enjoy your cool new custom A/C controls.

The results of my completly blue LED conversion:

Well I finished it tonight...a total LED conversion, from the gauges, to the HVAC, to the Headlight and accent lighting. Here's a few sneak peaks of the completed project, without the details.

So far I've done a reverse glow gauge overlay with the addition of LED backlighting to make the needles blue. I've also done the Healight switch mod to convert to a LED after the original bulb blew out 4 times in 4 months. Tonight I finished up my LED HVAC panel conversion. I've also got blue LED under-seat, under-dash, and on-dash accent lighting, on a switch that activates when the door opens or when I want them to. (Constant On, door-switchable-on, and off) Next is the Dome light conversion with blue LED accents.

For your 2003 Ranger, here are the bulb sizes. To convert to a LED, just get a "194 LED" or "3157 LED". Basically the base that holds the LED is all that matters, other than the shape of the lens.
