The rod that attaches the heat controls is out of place or broken and isn't moving the flap. Could be on the control end on the dash or the other end and/or could be a vacuum line fell off in this same area behind the controls.

SOURCE: I HAVE A 1984 CRX. HEATER DOES'NT BLOW AIR OR AIR

You are correct! If there is no air coming out no matter what setting you have it on, this is caused by the blower motor being burnt out.

Have a good one!

Why doesn't my 2001 Ford Taurus have heat but the blower motor works but only blows cold air.


Is the coolant level full ? Are the heater hoses hot to the touch ? Do you know where the heater hoses are ? Out in the engine compartment going through the fire wall into the passenger compartment . 2 hoses , one carries hot coolant into the heater core the other is a return back to the cooling system . If hoses are hot you have a temp. door not working . When warmed up what does temp gauge show ?
Temperature Control
The temperature control operates in the following manner:
  • Temperature control of the manual A/C-heater system is determined by the position of the temperature control knob (between COOL and WARM).
  • This control knob is connected to a potentiometer mounted in the integrated control panel. This potentiometer is electrically connected to the A/C electronic blend door actuator that operates the A/C air temperature control door.
  • The A/C electronic blend door actuator contains a reversible electric motor, another potentiometer and a printed circuit board. The wiper of the potentiometer is connected to the actuator output shaft and moves with the output shaft to indicate the position of the A/C air temperature control door.
  • Battery voltage is applied to the ends of each potentiometer. The voltage available at each wiper indicates the position of the potentiometer. The printed circuit board drives the actuator in whichever direction is necessary to make the actuator wiper voltage agree with the control wiper voltage.
System uses a reheat method to provide conditioned air to passenger compartment.
  • All airflow from the blower motor (18527) passes through the A/C evaporator housing where it can be cooled and dehumidified.
  • Temperature is then regulated by reheating a portion of the cooled dry air and blending it with the remaining cool air to the desired temperature.
  • Temperature blending is varied by the A/C air temperature control door which regulates the amount of cooled air that flows through and around the heater core (18476), where it is mixed and distributed.

Problem water in foot well ford kuga drivers side


Based on the limited information you gave, it appears as if your heater core is going out. If you live in a climate where it is cold and snowing and use the heater regularly, and also if the car is an older model, there is a great chance your heater core went out. The water runs through the heater core and through a process of convection, the heat from the warm water from the engine is extracted from the water a blown into your heater vents. When the core goes out, a hole forms, the heated water that runs through the heater core now leaks out and runs into your heat vent, and eventually on the floor in your car. The core is located under the dash board, and the whole dash will need to come out to repair it. Usually a costly job, as most vehicle manufacturers list the job as an 8 to 10 hour job. The air conditioner unit usually needs to come out also because it is a part of the heating/cooling system, so after the job is completed, your air conditioner will need recharged with Freon as well.

Air conditioner light stays on and i can't get the heater to work


You may need a new re-o-stat, or you need to bleed air from the heater core.

The air conditioning does not blow through front vents but through windshield vents, what is the problem?


This is a common problem on all Astro/Safari vans. The problem is a leak in the vaccum lines that control the vaccum switch responsible for changing air direction from the defrosters, dash vents, floor vents..etc.
Many of the problems that plaque the Astro/Sarfari vans and many other "Mini-Vans" is the build up of excess heat in the engine compartment. It\'s a tight place to put a V6-4.3 Vortec engine and the heat generated bounces back and cooks everything on the engine (coils, modules, sensors, wiring, and of course plastic vaccum hoses). No need to mess with your switches or anything behind the dash -- replace those thin plastic vaccum hoses to operate the vaccum switch (located just below the A/C canisters, to the right of the heater/ac blower housing) and your dash switches will magically send heated or cooled air where you want it.

My a/c won't blow cold and heater doesnt get hot


Is the heater working? Turn the A.C. off with the car at an idle. Turn the A.C. on and listen for the compressor to turn on. (should hear a click under the hood and the motor should change pitch. If no noise, the compressor is not comming on. The o-rings were bad about leaking on these cars, letting out all the freeon. If there is no freeon, the low pressure switch won't let the compressor run.
