1988 Trans Am HVAC Vacuum Line
Hi. My car is a 1988 Trans Am with a 350 TPI. Does anybody know where the main vacuum line enters through the fire wall into the engine bay from the heater box? My car is stuck on defrost and the vacuum line from the plenum is plugged into the Tee on the fire wall. One line goes to the cruise control and the one that is suppose to go to the HVAC is just hanging, not plugged in anywhere. Any Ideas?
