I have been pitting together the AC heater vacuum controls and thought I had an extra wire. Turns out I am completely missing a whole vacuum motor. After searching i located a reman vacuum motor and learned that their a'l the same except for one. However the bolts run parallel with the motor so...
I was getting no heat from heater core. So i pulled the hoses and flushed both ways with no issues. So I dumped water into the port that goes into the block and the water goes nowhere it just sits. Is this port clogged? Does the engine need to be running for it to push coolant through?
