i have purchused a 1994 s-10 blazer 4x4 4.3.....i have had all kinds of trouble with this thing and i am about ready to sell......but i cant be beat....the vaccuum is all messed up,,i bought a haynes book,,that was a waste of $..the front dif actuator is hooked directly to the engine, i know this is not right,and i have found vac lines that are cut and capped.....ineeda vaccuum diagram ! can anyone help ? please!!!

 

The lines that were capped were probably near the firewall on the drivers side, and that is normal. I had a vaccuum problem and saw that too. Went to check my fathers new jimmy and it was the same and buddys blazer as well, I cant be too sure for a 94 model, but I know 02 and up it was perfectly normal to find capped lines. What part of the diagram do you need exactly and why?

 

i really dont think its normal for the vaccuum ball to be unhooked,,,the heater to be unhooked,the cruize control to be unhooked, and the front actuator to be hooked up directly to the engine....the transfer case is the only thing really hooked up....and i am not sure its hooked up to the right spot on the switch,the vent from thte transfer switch is even unhooked...i need a vaccuum diagram for a 94 4.3 s-10 blazer....i can test the switch,with a vac pump,,but i dont want to damage it by putting vaccuum somewhere it should not be,,,,also the check valve,,where does that hose go...etc......i need to re-do the whole vaccuum system.....does anyone have a vaccuum diagram??? please help !!!
