Move the drive shift to Neutral then move the 4x4 shifter into 4W High or 4W low. Afterwards move the drive shift to drive. This is the best way; it reduces torque on the transfer case, therefore extending its life.
The drive switch to the lower right of the steering wheel has 3 positions: Left to right they are A4WD, H4WD and L4WD. When the switch is in the H4WD position, you are in High 4 Wheel Drive.
On a 2003 Ford Expedition : If you are driving on paved roads that are dry , for the best gas mileage , 2H But , you can also use A4WD ( Automatic four wheel drive ) on dry pavement A4WD is best for wet roads , snow , gravel because if the back wheels " slip " then some of the power is transferred to the front wheels
Yes.Yes.
The 4WD version of the Trailblazer has a rotary switch to the right of the steering wheel. The positions are 2hi, AWD, 4hi, 4lo. There is a N light for neutral. Rotate the switch clockwise from 2hi to AWD to let the computer select when to provide power to the front wheels. Rotate from AWD to 4HI to have 4 wheel drive. Remember to refer to the Owners manual for the maximum speed that you can travel in 4HI and 4Lo, and also how fast you can be going when you switch between modes. To go back, just rotate the switch counter clockwise.
Yes you can turn it with your hand when it is in 2-wheel drive ONLY.
"HI" is a latin word, its real meaning is horiontal roll, now u can easly understand the meaning of 2hi, 4hi, 6hi & 20 hi , for example 2hi mean two horizontal roll which is used for rolling the iron.
If the pavement is dry I use 2H , that has power going to the rear wheels only and gives the best gas mileage If the pavement is wet I use A4WD ( automatic 4 wheel drive ) that way if the back wheels loose traction some of the power is transferred to the front wheels

It will turn when driving because there isn't a disconnect from the front axle. It should be disconnected inside the transfer case.
The year, make and model vehicle would help otherwise, the lever should stay where ever you shift it to.
