Light above kick panel hard to shut off
 

The light above the kick panel on the driver's side won't shut off after closing the door - I have to slam the door about 2-3 times before it will go out. Now it's gotten to where if I hit a bump, the light will come on and the chime starts ringing. Where exactly is the switch for the light? There is no door-jamb button of any sort.
The one on the passenger side is OK.

None of the other interior lights are affected, just the footlight on the driver's side.

Anyone know where the switch is located?
