HVAC Control light

[JScelso]

The light on my HVAC control panel does not work, and I need to know how to fix it. I have taken the panel out but have found no bulb sockets.

This forum covers from 2003 to 2009. Please provide more information regarding your truck - model, trim level, HVAC - single zone / dual zone, etc.

I reviewed the 2003 and 2006 wiring diagrams. The diagram shows power to "AC Indicator", "Re-circulation Indicator", and "Mirror Heater Indicator" lamps are supplied from the HVAC Micro Controller and are all grounded at one terminal on the AC Heater Control center. The single air and dual air systems are virtually the same. I am going to guess that those lamps are not bulbs, but instead are LED's.

Do the Mirror Heater and Re-circulation lights operate?

Dual Zone, no bulbs, all soldered on to the board.

Single Zone, replaceable bulbs.

@petersonj they are micro incandescent bulbs which is the problem.

Thanks. The mirror heater light works as well as the one above it for air conditioning. It is not a dual system. The truck is a 3500 mega cab DRW ST model 6.7.
If the lights are LED can they be replaced, or are they built into the panel?

Single Zone, replaceable bulbs.

According to Ozzy, they should be replaceable.

Are these the ones?: ac control led lights 5013815AA. I picked this up from a previous thread on TDR years ago.

I ordered some bulbs from Amazon so I'll see if I can replace them when I get them. I wasn't sure when I had the panel open, but saw a video showing how to replace them. I'll let you know.
Thanks

If we talk about the 03-04.5 I know for sure, afterwards I don't know.

I ordered these from Amazon and they fit my control easily. Thanks all I now have lights again.
