01 Taurus a/c is working, but not blowing out the dash vents, only out the defrost vents. What do I look for, and how to fixing this problem. HELP!


The system to change from vent to defrost etc. it's all vacuum controlled. First thing I would do is look inside your engine compartment and look at all the black hoses close to the firewall. Check to see that they have no cracks, have come apart, this is also a good time to check your oil, and do a visual for anything that doesn't look tight or right. In Ford your temp is cable controlled but vents are all vacuum. Words case scenario you may have to take off that control panel to investigate further. One last thing if you can look under the dash tho make sure morning had been kicked loose. A good trick to use for an inspection like that is a mirror and flashlight. Let me know. Jim

Why wont my 2001 ford windstar blow out of vents ? only on defrost?


Air Flow Control
Air flow control is accomplished in the following manner:
  • Primary control is through the function selector knob , mounted on the heater function selector switch, which is part of the heater control .
  • The function selector knob has the following positions: OFF, PANEL, PANEL/FLOOR, FLOOR, FLOOR/DEFROST and DEFROST.
  • The heater function selector switch combines a vacuum selector valve with an internal electrical switch.
  • The vacuum selector valve directs source vacuum to various vacuum control motors (18A318) . Refer to the System Airflow Schematic and Vacuum Control Charts.
  • An internal single-pole electrical switch is also controlled by the selector. The switch controls the electrical supply to the heater blower motor switch (18578) .
  • The position of the function selector knob determines the manner in which the system will operate.
  • Each position of the function selector knob is detented for positive engagement.
  • You probably have a vacuum leak , Pull heater control panel an check for vacuum . A broke vacuum hose or The vacuum selector valve is bad ! Or check for a vacuum hose in the engine compartment being off somewhere !

What I am going to suggest will require a little research. You can get a wiring diagram by using the Web and entering a search for your year and model vehicle, wiring diagrams and then select correct diagrams from the search result.

Most fuses are behind a panel on the passengers side of the floor console. There may be Relays inside a Powerbox for the 4x4 module. Check to see if there are any Vacuum lines going to the 4x4 unit as some systems use both electric and vacuum to make things work. If you have a Rotary shaped 4x4 shifter, sometimes the knob splits behind the junction where the knob fits on the shaft. It is just spinning and not turning the shaft to really work. For Vacuum, use a Vacuum pump or inhale through the vacuum line to see if any vacuum escapes to check for bad lines or a ruptured diaphram.

I looked up the 4x4 unit and there were some with internal problems which had to be fixed inside the case. One reliable site I use did not have a record of 4x4 problems or TSB's for it, so there was no Recall for this problem and were few in number.

The knob, fuses, and Relay I mentioned are worth looking at as well as the Vacuum parts if applicable.

My 1997 ford ranger a/c dash vents won't blow


Vacuum supply starts on the drivers side of the engine. There is a vacuum line going into the brake vacuum assist from the manifold. branching off of that line is a double line that snakes under the intake manifold, behind the valve cover, along side the valve cover on the passenger side headed to the front of the engine. Then it curves to the right side of the engine. One set of hoses from this line goes to a valve control (red and green i think). The other line goes to the vacuum storage ball, it should be black. The vacuum circuit continues out of the ball in another black line that snakes into the firewall. It goes under the heater core black box and disappears under it. Now go into the passenger compartment and drop the glovebox. look to the back right you will see a black and a white vacuum line coming out of the firewall. The black line is your vacuum supply from the engine. It goes up to a little rubber manifold. disconnect the lines coming from the dash switch and check for vacuum on the manifold where the black line is going in. The white line controls the cabin air intake under the glovebox and the thermostat shutoff under the hood. It should only have vacuum when the switch is in a certian position, AC probly. The other three lines coming off the rubber manifold snake behind the dash vent door assemble and come out near the gas peddle. The red one controls the dash vent. apply vacuum to the red hose and see if the vents go to the center dash position/AC. The yellow and blue? ones control the floor vent control near the gas peddle. yellow gives you half floor and half defrost. blue gives you all floor. you can use a small vacuum line to connect the black vacuum supply to each individual line on the manifold and check the function of each vacuum control assembly individually. I hope this helps. On my truck each control unit works fine when i apply vacuum to them individually but when I hook the dash switch up to the rubber manifold it goes to defrost. I tried changing the dash switch and the lines running from the switch to the rubber manifold and the vacuum ball under the hood, nothing works. I suspect I may have leak i just haven't found yet. next step is to get a vacuum gage and start checking the amount of vacuum i am getting at each vacuum line. I'm sure it is supposed to be getting a specific amount of vacuum and will not work if the vacuum drops below a certian level due to a leak in a line somewhere? God bless.

How can I remove the factory stereo?


The plastic piece surrounding the radio has four screws holding it. Two just above the controls for heater/fan, one when you open the glovebox, and one in the same position as the glovebox one on the other side (drivers side). Sorry, but it's a bit hard to explain in words. You'll need to crouch down and look up for the screws, they're out of sight, mounted in the bottom parts of the plastic. After the four screws are removed, use a flat screwdriver in the two vents above the radio to pry them down away from the dashboard, and the whole piece will lift out. Oh, just remember to take the knobs off the radio if it's stock, and the knobs off the heater controls before you start, or they'll be flying across the car when you pull the plastic surrounding out.

If it's attached to the diff housing and not to the box on the r/f axle (if you have one) it is a vent hose. Just secure it anywhere out of the way on the firewall. Don't pull it tight or when the axle moves it will fall off again!
