99 chevy tahoe. 2 wheel indicator light on dash keeps going out, then will come back on. Will switch back and forth from 2 to 4 wheel drive without any problems. Light just comes on, then goes out, then comes on. No specific pattern. Have recently changed the accuator and motor for 4 wheel drive after having a problem with it switching into 4 wheel drive and not coming out. This light is frustrating. Please help.

Check the wiring to the actuator to make sure there is no corrosion in the plug. Also, make sure the pins haven't pushed back only making contact once in a while. Also, check the 4wd relay under the hood to make sure it is tight. Finally, check the wiring to the rear of the switch making sure it is tight.
