there is a vacuum actuator under the hood next to ur battery, it has a vacuum line runnin into it and a cable that connects to the vacuum diaphragm and goes down to ur front axle, check the vacuum line runnin into it and see if it is loose or has came off

I have a 89 s-10 blazer and also having 4x4 problems, the actuator on the 89 is suppose to be under the battery tray
