my 2006 chrysler 300 a/c control console lights not working, what may be the problem

chrysler dealer told me i have to buy the whole unit about 160 bucks

I have a 2005 Chrysler 300 with the same problem. A little research discovered the manufacturer put bulbs instead of led's and bulbs burn out. I opened my climate control and all 12 bulbs were blown. The original bulbs are not available to the public. Radio shack has a good replacement bulbs for about $2.69 ea. Got mine off ebay for $1 ea. bulbs are a T1 14v 8a, radio shack will know what your talking about. I heard one gut used bulb #7219, but I got bulb #7382. 7219 is small than original bulb and 7382 is larger (again, original size not available). needs to be soldered with rosin core solder. check youtube for soldering tips.
