My 1995 Ford Explorer Won't Engage the 4-Wheel Drive
- 1). Wait until none of the SUV's wheels are slipping if you are unable to shift the Explorer into four-wheel drive from two-wheel drive. Then rotate the dashboard knob from the "2WD" position to position marked "4WD Auto" to engage four-wheel drive. You may hear some clunking and under-floor noises, but that's normal.
- 2). Stop the SUV if the Explorer won't go into "4WD Low." Press the clutch down, or, for automatic transmissions, place the Explorer into "Neutral." Then rotate the switch to the "4WD Low" position.
- 3). Wait for a minute if the Explorer still won't shift. Shifting may be delayed if the ambient temperature is below zero. Other variables that can affect the speed of shifting include tire pressure, worn tread and loading. Check the sticker on the driver's-side doorjamb and make sure that you are in compliance with the requirements printed there.
