My center diff light doesn't go on when I lock it. I have done the parking =
lot test, and it passes. The diff absolutely locks and stays that way until=
 I unlock it. Once in a while, if I forget to unlock it and I reverse out o=
f my driveway or something, when I feel the binding up, the light will go o=
n until the car stops (because of binding). What can be the problem?

How do I check the switch that turns the light on?

Reply privately, please.

TIA!
