I see 5 all together
Fuse F11 (10 amp). Feeds the A/C clutch relay and the 4x4 center axle disconnect solenoid.
Fuse F111 (30 amp) feedsClockwise (cw) motor 4x4 relay, counterclockwise (ccw) motor 4x4 relay.
Fuses F20 (10 amp), F29 and F30 (15 amp) are for the Powertrain control module (pcm) (AAA1001) V4WD
If they are all good you need to check for Trouble codes I'm pretty sure your cluster will do this check for you. You have to hold down on the SET UP and RESET buttons (these are two of the three buttons on your dash next to your ignition key hole) then turn your ignition to run but do not start. At this point you can read for codes, one of the three buttons scans you through it I cant remember which one at the moment though. These are the codes listed in my manual that are shown for a 4wd problem. If you see any of these post which one and I'll post what it says.
B1317, B1317, B1342, C1979, C1980, P1824, P1826, P1827, U1900, U2023, U2051
