This problem actually began while the vehicle was under warranty, but I was told that bulb replacement was not covered. When I found out there were no replaceable bulbs in this unit, it was too late. Most of the LED (or whatever) indicator lights in the climate control panel are out. This makes it impossible to select anything in the dark unless you turn on the dome light or have a flashlight handy. I was advised that the entire climate control front panel would have to be replaced. Too much money.
