my 92 S10 blazer 4wd hi will not work, sometimes
if you disconnect the battery for a while it will work for a few days then it stops again.

There are a few things to check.
All vacuum lines from engine to actuator (under battery tray)
Actuator cable to diff damaged
Faulty vacuum switch
Transfer case linkage
Transfer case selector ring
Is this a push button system or lever actuated?
Does 4 low work?
