A couple weeks ago the 4-wheel drive in my 95 GMC Sierra quit working. It has the shift lever in the floor. The 4-wheel drive indicator light don't come on. If the actuator has quit working will the 4-wheel drive indicator light stop working also ? And if you remove the actuator but reconnect the wires, then engage 4-wheel drive, shouldn't the actuator do something if its working correctly ?
I would think so..
SOURCE: 4x4 still not working
you could have problems in the shift control module.or faulty switch in dash.

The resistor is most likely bad but should still work on the highest setting.Would check pigtails to the resistor and to the blower motor for burnt or discolored wiring.You can try tapping the blower motor and wiggling the wiring harness too see if it will work on the highest setting. It is possible that the blower motor is bad as well typically when you lose the speed selection it is the resistor but you should always have high speed.
SOURCE: Front wheels won't engage when in 4 wheel
Then the problem would be in the differential. something came loose or broke off the actuator on the inside

Drive forward, put it in neutral, the into reverse. If you have not used the 4wd for awhile it will need vacuum to activate and disengage
SOURCE: Front drive, 4 Wheel drive won't engage
Check the switch on the transfercase remove the vacume lines if there is oil in them the switch has to be replaced and the lines should be cleaned out you should also check under the battery tray to make sure the boot is not ripped that controls the leaver to engage the front axel
