With your engine running, pull your transfer case into 4WD. There's a vacuum actuator on the right inner fender under the hood that engages the front end, this should be pulled in by engine vacuum.

My 85' S-10 Blazer had a bad vacuum switch on the transfer case. I was able to get home one night with a C-clamp holding the actuator in.
