FORD AEROSTAR COOLANT PROBLEM

1996 Ford Aerostar • 24,000 miles

When on VENT for heating, after driving for 10 minutes or so, the heat gauge will slowly move to the L on "normal" and then drop back to the O. The rear heat blows ambient temperature.

I have replaced the small single-line vacumm switch that goes to a "t" and then to vacumm reservoir & into heater plenium.

Water pump is new.

Check to make sure rear is gettinghot water on both hoses then check actuators. Check coolant level if low have pressure tested for leaks.
