I am sorry for the long waitwhen you first key up the ignition in the truck will the 4WD lights all bulb check or light up on the switch then shut off with no case position ?or the switch lights will not even bulb check ?

The 4x4 switch lights do not light up, , is that What you mean by buld check ?

Expert:  Gary replied 2 years ago.
yes it iscan you first be sure the fuse called 4WD in the inside fuse box is good and see with the key ON if that fuse shows 12 volts at it also in the under hood fuse box check the fuse called ATC for it being blown and make sure it has 12 volts at it with the key ON

if those check out good then disconnect the battery for 5 minutes then touch the 2 battery cables together for 2 minutes then reconnect both battery cables will it bulb check and work after you do that ?
