Today, I replaced my stock stereo head unit on my 99ML.
It sounds great and everything works, EXCEPT for the illumniation around the climate controls - these are out!

All other dash and instrument cluster lights work. However, the climate control lights are out. Any ideas as to what may be the problem? The climate control WORKS, and all the dials work... so it doesn't appear like it's disconnected - just the light don't work.

Does anyone have a service manual or wiring diagram they can look up to determine if it's a wire I need to ensure is plugged in, or a bulb that I simply need to replace?

If it's a bulb, where and how should I replace this bulb?

Your thoughts much appreciated

i had the same problem, all the little red lights worked except for the main one that illuminates the display screen. if you take out the unit, on the bottom theres a white round socket that holds the bulb, turn it half way and it should come right out, just change that little L.E.D. bulb. hope thats your problem, it worked for me.
