Question about 1998 Chevrolet S-10 Pickup
When I push the 4hi or lo,,, I hear a clicking sound under the glove box in the side panel area 4wd will not engage only stays in 2wd
Your problem sounds like either the transfer case control module located where you hear the clicking sound, or the actuator on the transfer case itself.
try unplugging the transfer case control module and then plug it back in, try engaging 4wd again (make sure your in neutral, coasting at 1-2 mph might help as well) if it still doesn't work check the actuator itself to see if the actuator is trying to engage. if the actuator is trying to engage but doesn't, take the actuator out and check it for wear or damage. if the actuator seems fine and it responds to the buttons when pressed i'd go after the transfer case control module as the culprit. ran into that a few times on those s-10's. 3 out of 4 that i've seen were fixed with a new tccm. 1 of the 4 needed an actuator, check your local junk yard for a working tccm or actuator.
hope this helps!
