Hello mrdavies, yes, the climate controls are illuminated. The climate control assembly contains 4 internal lamps. They are supplied voltage from the Central Junction Box (fuse panel) to the left of the sterring column, fuse F132, 10amp. The circuit also supplies voltage to the illumination of the air inlet mode switch/ac switch/defroster switch/hazard flashed switch/floor shifter. Are those switches illuminated?
