Sable V6-3.0L VIN U (1999)
An illumination bulb in the control assembly provides backlighting for the vacuum fluorescent display window. When the panel dim control on the
headlamp switch is adjusted, the intensity of the light from this bulb will increase or decrease depending upon the adjustment. (The backlighting on the
control assembly, as well as in other instrument panel locations, will dim whenever the headlamp switch is in HEAD).
