Okay, thanks for the reply.
In and ACC mode, the LCD lights are on, the leds are off for the fan speeds and the air flow modes .. but no background lighting for the overall buttons.
In the parking mode, the same, LCD lights are on, the leds are on for the fan speeds and the ir flow modes .. but no background lighting for the overall buttons. the glovebox light now works. but no background lighting for the overall buttons.
When the headlights come on, the lCD's for the radio and the clinate control go off, the led's stay on, but no background lighting for the overall buttons. the glovebox light now works. hmmm
I appeciate your help in this matter. driving at night, trying to figure out the heating system is very tricky. that backlighting of the controls is really impirtant.
Hope this helps.
