Question about 1994 GMC Jimmy
If you can hear your transfer case switching then the problem isnt with your transfer case. their are three vaccuum lines that run out of your transfer case switch and if they are dry rotted or burnt in two from the exhaust manifold which is pretty common your four wheel drive will not engage your front differential. go to the auto parts store and buy about 15 feet of 7/32 vaccuum line and trace all the lines and replace them all. that will more than likely fix your problem.
