It takes 3 minutes to pull that swith from the rear of the front axle, passenger side. Use a 7/8 OE wrench. put it on the bench and with a continuity tester probe both contacts and look for continuity when the switch is depressed. I've seen everything from loose switces to loose vac moters to broken vac lines and wires. The next connector after the one on the switch itself is on the passener side behind the front bumber. The harness that carries it is attached to the bottom of the fan shroud. You'll typically find the problem around the front axle area though.

 

Ill second that! A lot of the time its just a bad actuator if its not going into 4 wheel, i like the cable actuator kits. But if the light just goes on and off you probably just have a bad connection on the sensor on the axle.

Im new at this, mine is doing the same thing, will engauge in the transfer case but front tires wont spin. My light on the dash comes on, so would my problem still more likely be the actuator?
