Hi Everyone!
I am new to this forum and have a question/problem I hope you can help me with. I have a 2005 Grand Chreokee Larado and the lighting behing the HVAC Head is out on the left side of the panel. The right side will come on dim if you tap on the panel. Any ideas on what is causing this and is it an easy fix?
Any help would be appreciated !

you will have to replace it with a new unit or do what i do and just lightly tap the knob and the face plate unit until the light come back on again. some one on here has bought new lights and soldered them in the board

seems like a common problem, seen it a couple times on this and the other board. I also saw it in a friend's WK.

If you are under warranty get it replaced. If not, you have to buy a whole new board. Now thats some genius Chrysler engineering for you.

Other option - you can solder on new leds, do a search here and jeepsunlimited. Its much cheaper than a new board but might be tricky if you've never used a soldering iron - but not that tricky IMO. The key is to find the right size/voltage leds.

The HVAC illumination bulbs failing is a common problem.

The LEDs over heat and short out. The control head is a sealed unit so the bulbs are not servicable. Not unless you are experienced enough to crack it open and solder your own LEDs in place.

My 2005 is under warranty, so I took it back to the dealer. They replaced the control head.

No cost to me, but there was a price on the work order. Perhaps an internal charge to the sales dept.

The part number is: 55111009AO

part: $94.38

I'm not sure if that is the retail price or dealer internal.

I did notice that the knobs have a chrome edge to them, where as the orginals were all black. So I am hoping this new control is a newer and improved part.
