JIMMY SLE

1999 GMC Acadia • 6 cylinder 4WD Automatic • 190,000 miles

I have a '99 gmc jimmy SLE and I push the button to go into 4HI or 4Lo I hear it engage but when I drive only my rear wheels spin. What would cause this to happen. Can it be a simple vaccuum problem. The lights on the dash say I am in either 4Hi or 4Lo but the truck is still in 2wd
