Hey I have a 92 s-10 blazer. 4x4. I think I need the part that lives under the battery that actuates the front diffential. the truck wont engage in 4 hi or low. Whats the name of the part Thanks Steve
Thermal linear actuator in that year I believe about 80 bucks at checker auto parts
Thanks guys
S trucks don't use the thermolinear actuator... they use a vacuum actuator.

'thermal linear actuator' mounts on the axle
My bad thought they were all changed to TLA
Change the Vaccum Switch on the Transfer Case First.. It is more in likey your Problem.. Ps The hoses running to this switch are close to the exhaust and They Break Check for Vaccum leaks at this switch !!

if the hoses are toast, re-route them
go up the left frame rail to the brake booster, then across the back of the engine
takes about a half-hour and 25 ft of vac hose
