Gotta clear the code ,than restart engine, if code is persistent again,then there is a blockage in your intake or plenums
On a 1998 Windstar the vacuum reservoir tank is under the hood in the back left of the engine compartment when standing in front of the vehicle. Mine has a red and black vacuum hose coming out of it.
The vacuum modulator on aÊ2001 Ford Windstar is located in the front left area under the hood. It is connected to the transmission by wires and tubing.
yes
Sounds like you have a vacuum leak - -bad or loose hose or defective diaphragm in one of the vacuum motors
The blend door is vacuum controlled. Any vacuum leak in the engine system can cause the door to not function properly. Check this system first. The door could be physically sticking but a vacuum leak is a more common problem.
Yes, this really can happen. The transmission modulator ruptures and vacuum system system draws out trans fluid into engine oil thru vacuum pump into engine crankcase. Been there, done that. I replaced the modulator valve and dropped engine oil.
The transistor replaced the vacuum tube, allowing radios to get much smaller and portable.
Probably a vacuum leak
The air selector valve (MAX AIR-off- to defrost) is a vacuum switch that runs vacuum motors in the air ducts. If the switch fails or if the vacuum supply from the engine fails, the selector function will fail. The default mode with no vacuum is flow to air conditioning vents. The vacuum hoses resemble a wire and from the engine is usually red and black
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
You probably have a vacuum leak. Check under the hood for a disconnected vacuum hose.
The engine does not produce enough vacuum to be usable.
