Four problems related to transfer case have been reported for the 1999 Ford Ranger. The most recently reported issues are listed below.
While merging onto the highway the 4x4 high light came on with the selector switch still in the 2-wheel drive position. Stopped the truck immediately and restarted the truck. Once more attempted to accelerate up to highway speed, when the 4x4 high light again flashed on and off. At approximately 50+ mph the truck slammed into 4x4 low. The selector switch remained in the 2-wheel drive position.
The four wheel drive stinks it come in and out of four wheel drive and there is always something messed up in it.
Vehicle would not switch into 4wd when dealer notified I was told that I had to be in neutral to switch into 4 wheel drive. After three additional visits to the dealership the switch motor was finally replaced. Dealer did not want to admit the problem was with vehicle.
Consumer placed vehicle in 4-wheel drive, but vehicle would not remain in that position. It would disengage out of the 4-wheel drive. Took vehicle to the dealer, where the mechanic attempted to repair the vehicle six times, but the problem still exists.
