I'm not sure about that 1 being the right solenoid. And the vacuum style wasn't on the later s-10's as they went to electric soleniod. You should be looking at the front rearend, and it should be on the pass. side of the 3rd member. It will have wires plugged to it. Have some one to try pressing the button while you listen or feel to see if it makes a click or clang. If it doesn't then check to see if it's getting juice. If so, then replace it and your ready to go again. Hope this helps.
