Where is your vacum attached to the engine. I have the hose and elbow but can’t find where it’s attached to draw vacuumFYI, I decided to unplug the heater control valve vacuum tube that goes to the solenoid and my heater immediately started blowing hot air. Previously I had only tried unplugging the vacuum line from the engine to the Solenoid and it made no difference.
I tested the voltage going to the solenoid and it was 12V when the cold air is on and 0V when the hot air is selected. I assume that’s working properly so I must have a bad solenoid.
Will update after I replace with new.
