when you first key up the truck will the 4WD lights all light up and bulb check then shut off ?

if nothing even when you key it up can you check and see if the fuse called 4WD in the inside fuse box is not blown and see if the fuse called ATC in the under hood fuse box are good ?

Customer: replied 1 year ago.

Expert:  Gary replied 1 year ago.

if so disconnect both battery cables for 5 minutes then touch the 2 battery cables together for 1 minute then reconnect both battery cables to the battery will it work after doing that ?
