2001 jimmy wont shift to 4 wheel high

[shade5]

01 Jimmy wont shift to 4 wheel high. It will shift to 4 wheel low but light flashes while in 4 wheel low and its hard to get to shift back into 2 wheel drive.

in order to put into 4 low you need to put the truck in neutral then wait of it to lock in... if you dont then the light will just flash... if it wont shift into 4 hi then there is an isue with you locking hubs... and have your transfer case checked out
