4 wheel drive light on dashboard


Hi all,

My 4 wheel drive light on the dashboard does not light up. As I've only just got the car, I not 100% sure whether the car is shifting in to 4 wheel drive - should I be hearing a click at the front or rear when I transfer in to 4WD and move forward? I've got the automatic hubs with the 2H 4L 4H stick by the gear lever.

I've checked the bulb and it's working fine. Presuming the car is moving in to 4 wheel drive, what could it be and how could I fix it?
