Rear Door Services Switch Panel - Lights Out
I assume the rear door services switches (heater, wiper, washer) are meant to light up at night as they have bulbs in them. Mine have never seemed to work. The switches operate correctly - and the rear-heater warning light on the dash comes on correctly. However, the switches never illuminate.
I swapped the bulbs for LED's assuming the bulbs were just out - but didn't help. With headlights on, there is no voltage across all 3 of the bulb holders.
Are the lights in these switches fused independently of the switch operation? Any suggestions?
I tried looking at the electrical wiring diagram in the manual - but my head just exploded.
