check all wire conections also replace the actuator on the front axle but check for power there first if you have power replace that switch as well .

I had the same problem on my 90 K1500, it was the 4 wheel drive actuator unit itself. Bout it at the local parts store for 30 bucks and installed it in 10 minutes or less - and vavoom! 4 X 4 back in business.

Ok, this is probably going to sound greek if you have no automotive experiance, so here goes:
There are 2 possibilities I can think of at the moment depending on your 4wd system, however there are several things that can cause this
If you have a Push button 4wd (you push a button or turn a knob) the system engages using actuators or sylinoids meening you turn the 4wd on, the switch sends power to the selector option (high and low) and the 4wd light on the dash. the selector determines where the actuator/silenoid engages (either high or low) in the transfer case. However the actuator or silenoid can be faulty and yet the system will say 4wd is on because the switches still sending power to the 4x4 light
The next setup is the manual linkage set up, and given the year of your kia I doubt you have this setup However I am going to go through it anyway.
With a maual linkage setup you engage the trasfer case maualy using the 4wd shifter. Ironically on newer manual shift 4wd systems the dash light is still triggered electrically by location of the shifter not what is going on in the transfer case (Ah a flaw in the design) So if you linkage is loose/bent/damaged or somehow disconnected your 4wd wont engage but the light will still show that it is! Hope this helps
