my four wheel drive

could be as simple as banging the transfer case with a rubber mallet or the computer might forget where it is try disconnecting your battery. if that doesn't work message me ill be willing to help out.

check the fuse,will be numbered .and will say 4x4,switch to enguage 4x4 could be stuck,push on it several times to see if it comes out of 4x4,bad case,their is a small motor on back of transfer case,could have gone bad,I think it is just stuck,just keep pushing on the switch.
