It sounds like you need a new actuator. there is two things that lock in when you use 4x4. one is the transfer case and the other is the front diff. the front diff is turned on by an actuator. if you have a problem with the actuator the front axles wont lock in. even though the transfer case is engaged.
Engaged is a verb (past tense of engage) and an adjective (an engaged couple).
Means engaged to be married.
No....he not engage but marry....
She isn't engaged with anyone.
The past participle is engaged.

adenas are unable to engage in anything
try replacing the actuator valve on the front axle
faulty actuator switch. GM had some problems with these.
do you engage 4WD manually or via the button on the dash? if its the latter then your actuator switch is probably bad. tweek
Answerchange your 4x4 actuator It could be that or in the switch. But probable it is the actuator on trans mission..
