I have a 2001 f-150 with the electronic 4wd. When i shift into 4 low the t-case engages as well as the axels but the dash light does not come on, is there a switch on the t-case that could be busted or what else could i look for?

 

it may be something as simple as a burned out light?

 

Does the light come on when you first turn the key on in the truck? If not, the bulb is burned out.
