Question
i have a 97 s10 blazer that wont go into 4x4. the buttons on dash seem fine, the transfer case control sounds like it is engaging and the vaccuum actuator is staying engaged. which part would you think needs replacing?
Mike,
Without actually looking at the Blazer, it's almost impossible to guess what part needs replacing.
Do you have an electric, or vacuum interlock on the front differential. It's possible that the transfer case is locking in, but the front differential isn't.
I would get a repair manual for the Blazer and check out the trouble shooting section on the front differential and the transfer case.
These can be purchased at most auto parts stores for, around $20, and are great sources for checking out problems.

Experience
40 plus years of 4 wheeling in a variety of vehicles. At the present time, my major off-road rig is a 94 Jeep Wrangler with a spring over and a 1 1/2" suspension lift. This gives me a total lift of 7" or so. I have lockers front and rear. I have removed the track bars, and sway bar for maximum articulation. I am running a stock 2.5 ltr 4 cylinder with a Jacobs ignition along with a cold air high flow filter. It has 4.56:1 gears with a Dodge NV4500 transmission along with a 3.8:1 Atlas II transfer case. This gives me a final ratio of 105:1 in low gear/low range.
Other vehicles I own, are a 96 Ford F-250 with a 6" lift, posi rear end, 36" Hummer tires, 5 speed with a fuel injected 460 ci engine, an 87 Samurai with an 8" lift, Ford 9" rear end with a spool, Chevy Dana 44 front end with an electric locker, 5.88 gears, 16% reduction in high range and a 6.5:1 low range with 35" Baja Claws, and a stock 2003 Grand Cherokee Overland.
Trails I have run are the Rubicon (10 times), Dusey Ershim, Fordyce Creek trail, McGrew trail, several trails in Moab, Utah along with local monthly runs.
