you can also check the 4 wheel drive vacuum switch on top of the transfer case...got mine for 10 bucks from parts store...fixed the problem

A VERY COMMON FAULT!
Kia us a dim design that works on air, so the light on the dash may light up green...mine does...but no 4x4.
Test one, look inside the engine bay,(2Litre petrol) on your left hand side, to the left of the actual engine is the solenoid device that "switches on" the vacuum to the front hubs. This is easier that you would think. If you look at the left side of the engine, there are two pipes coming out (left side) one is thick (break system. DONT touch) one is thinner and soft rubber. Follow this tube, it goes into a small black cannister which is a resvoir and one way valve...the tube then outputs into another device (solenoid) which has 2 wires on. The tube then splits under this in two. The test is simple, with the engine running, and 4 wheel drive engaged pull the tube apart after the solenoid. Put your finger there you should feel a nice strong ****. If it does **** put it back on. If it does not **** it needs to be removed and cleaned. This is simple to unbolt and all you do is pull the rubber bung of the bottom, and the two tubes and spray break cleaner inside. reassamble until you get to feel the vaccum.
test 2 Now look behind each wheel, you will see a thick hose wrapped in a spring, this is the break system, do not touch this. There is a thinner flexible hose attached behind the wheel, you will notice that these have no securing system just push fit. Remove each of the in turn and test for vacuum.
Leaks here are common and easy to fix.
The bad news if you have vacuum, and still no 4 wheel drive one or both front wheel hubs has a leak, and the bad news is, it needs a garage to fix it, and to replace the seal a £5 part you have to ruin a £100 part.
Test the vaccum, pray. Otherwise ask, doe you really need to spend £250 to sort this?

On the full size, the front actuator is electric, not vacuum.
When in 4wd mode, a switch on top of the transfer case conducts 12 volts out to the actuator. Wire #50 (brown) is the 12v feed, and it conducts to the light blue wire (#900) to the actuator.
When shifted out of 4wd, the switch opens up and no voltage goes to the actuator.
Check voltage at the connector for the front actuator (at the front differential - it looks like a large bullet that threads into the front diff.) If it has 12 volts, the actuator is the problem. If it does not have 12 volts, check the transfer case switch and the power feed to the transfer case.
I'll assume it is the actuator, if the plug to the actuator is getting 12 volts when in 4wd.
The way this actuator works, is it is a sealed chamber that gets heated by voltage. When it heats, the pin in the end swells and pushes a shift fork in the front differential. The shift fork engages a spline on the passenger side of the differential, and boom! you have 4WD.
GM offered an upgrade to this actuator that is a motor instead of a heated device. However, it requires a small harness addition, a spacer, and a new actuator. It is about a $150 to $200 option.
If I were you, I would buy a new heated actuator. They are available at most auto parts stores, and are about $90. They are also on eBay for about $55 plus shipping. These are very easy to change - just thread out the old one, and thread in a new one.
Good luck, That actuator is usually the problem 90% of time but check the fuse first in your fuse box.
