The heater works properly stopped at idle. Upon acceleration, a cold air vent opens & blows frosty air into the heat duct.....quite unpleasant! If driven VERY carefully (very minor throttle input) the heat will operate properly at all speeds. There is obviously a problem with a vac solenoid somewhere...but I have not been able to locate it....nor any other apparent vac issue....
