I changed the value cover gasket, on a 1990 crown vic ltd 5.0 motor and some vaccum line came loose. How do I find where they go?

one with constant vacuum should not go to distributor dashpot if it has one. check valves or sensors for a nipple. maybe somewhere on the heater box. try to download a vacuum line schematic.that will show you where they all hook up.

1996 crown victoria has no heat

the temp blend door may not be rotating from the a/c evaporator to the heater core opening.

Could be the motor on the blend door or the temp control knob.

Do you have manual a/c or electronic temp control?

If it's the a/c door electronic actuator motor, it's on top of the plenum. Have to remove the instrument panel for access.

Hope it's the temp knob on the control head.

top one is the circuit you are looking at
