On my 1995 chevy pick up it has a stick shift for the four wheel drive. It goes into the 4 high position but will not go into 4 high at the front wheels. I am stuck on the grass at home and cannot get it off to try while I am moving. I have only just bought the truck and it did work when I went on a test drive.
Check to make sure none of the vacuum hoses to the front axle are damaged or disconnected.

Make sure there is power to it. Also, If I recall, in 95 the front diff was vacuum actuated. Double check that and make sure there is vacuum to it. Finally, make sure the linkage to the transfer case is properly attached.
