4x4 ControlModule mounted in the dash or the right interior passenger KickPanel,
& 4x4 ShiftMotor on the backside of the 1354 TransferCase directly under the drivers seat floor,
are both notorious failure items for Explorers & Rangers.
DC motor brushes & control relay contacts wear out
& if you don't cycle the 2wHi~4wHi~4wLo at least once a month, the ShiftMotor tends to stick.
Unbolt the shift motor from the TransferCase, leaving the wire harness connected,
cycle dash control switch to confirm if ControlModule & ShiftMotor are working.
If Motor goes thru it's motions proper, problem is likely the Motor is weak & needs replacement.
If Motor does not cycle proper, problem is likely the ControlModule is bad & needs replacement.
Get FordMotorCraft# XXXX~XXXXX~XX off of both parts & google.
Several variations of Module & Motor are NOT compatible\interchangable; be sure first+middle part numbers match.
Each costs about $75 if you shop around. Both are relatively easy to replace.
Hope this helps. Links to more info on these at
