This seems to be a problem with the actuator for the mode door in the heater housing. It shouldn't require replacement of the heater housing, but may require a lot of work to get to the heater housing (possibly removal) to replace the actuator. If you want air to be directed to the floor or the dash vents, you will have to have the actuator repaired/replaced.

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 !

How do i fix a stuck blend door on 2010 dodge nitro?


I would pull off the blend door actuator and swap it out with a new one. Or another option is to swap it out with one of the other actuators. The blend door actuator is interchangeable with the actuators for the mode-air doors and the recirculation-air door.

Disconnect and isolate the negative battery cable.

If equipped, remove the silencer from below the driver side of the instrument panel.

Disconnect the wire harness connector from the blend door actuator located on the driver side of the air distribution housing.

Remove the two screws that secure the blend door actuator to the actuator mounting bracket and remove the actuator

Hearter temp control was blowing too hot, now only blows cold


Clicking sound you hear is the worn brushes in your blower motor. At this point the blower moter may or may not start with the switch. THe blower motor is faulty so I would change that first, then check for vacuum leaks or faulty selector cable for the heat blend door. It could have came off door side or heater control side.

I have a 2010 ford escape..prob started as a coolant leak..took it to ford dealer, they repl water pump..a week later we noticed when u stop a red lite heater starts blowing cold air..took back to...


The performance of the heater indicates low coolant level. Pretty strange about the multiple water pumps, but if is is under warranty, you need to keep going back to the dealer. They must be missing something...

Aircondition blows hot air on normal but blows cold air on max


The temp blend door rotates between allowing heat through the heater core, or cold air through the a/cevaporator, or a blending of the 2 by being anywhere between the two.

I would check the heater a/c control head first and hope it's just the control head.

here is a descripton of the system.

Section 12-03A: Air Conditioning, Heater System, Manual, Ranger and Explorer 1996 Ranger and Explorer Workshop Manual
DESCRIPTION AND OPERATION A/C-Heater System, Manual The manual air conditioning/heater system used in these vehicles is a split-case, blend air design. This design includes the following major components:
  • An A/C evaporator housing (19850) which is attached to the engine compartment side of the dash panel (01610). This assembly includes: (1) the A/C evaporator core (19860), (2) the suction accumulator/drier (19C836), (3) the A/C cycling switch (19E561), (4) an internal, A/C evaporator core orifice (19D990) located inside the inlet line to the A/C evaporator core, (5) a blower motor (18527), (6) a blower motor wheel (18504), (7) a heater blower motor switch resistor (18591), and (8) the A/C evaporator case (19897).
  • A heater air plenum chamber (18471) which attaches to the passenger compartment side of the dash panel. This assembly includes: (1) the outside/recirculating air inlet door, (2) the panel door, (3) the floor defrost door, (4) the temperature blend door, and (5) the heater core (18476).
  • Other components which link and/or control the heating and air conditioning systems include: (1) the A/C control (19980), (2) the ducts and registers, (3) the windshield defroster hose nozzle (18490), (4) the control cables, (5) the vacuum lines, (6) the refrigerant tubes and hoses, (7) the A/C compressor (19703), and (8) the A/C condenser core (19712).
050240f.gif
The A/C control (19980) assembly consists of three main parts:
  • The function selector knob, a vacuum selector valve combined with an internal electrical switch.
  • Heater blower motor switch (18578), an electrical switch that provides four speeds of A/C blower motor operation.
  • A temperature control knob, which controls the position of the temperature blend door mounted on A/C evaporator housing (19850) assembly.
---------------------------
Temperature Control
The temperature selector actuates a variable resistance switch. This switch varies the voltage to an electric actuator used to position the temperature blend door. Positioning the temperature control in any position between COOL and WARM causes the temperature blend door to direct more or less outside air through or around the heater core (18476) for whatever proportion of heated or unheated outside air is desired. The air blends together as it leaves the heater core and enters the heater air plenum chamber (18471) for distribution.
---------------------------
System Airflow Description Air is drawn into the system by the blower motor (18527) through the outside-recirc. door opening. The air is blown through the A/C evaporator core (19860) and then the heater core (18476) (when the temperature control is moved toward the WARM position). When the temperature blend door is in the maximum COOL position, the air bypasses the heater core. When the temperature control is moved to the right, away from the maximum COOL position, air passes through the heater core where it is warmed, and then mixed with the cool air before it is discharged through the registers. OFF
With the function selector in the OFF position, the outside-recirc. door is in the recirculated air position. It is closed to outside air and no air passes through the system. The blower motor is off. MAX A/C
NOTE: No temperature modulation is possible in the MAX A/C position.

In the MAX A/C position, the outside-recirc. air door is in the recirculated air position. All of the air discharges through the panel registers except for a small amount of floor bleed. The A/C compressor (19703) operates in this function control setting.
--------------------------------
You have to almost remove the dash to get this part out.
Removal
  1. Disconnect battery ground cable.
  1. NOTE: Refer to Section 01-12 for instrument panel removal and installation procedure.

    Loosen instrument panel (04320) and pull back from cowl.
  1. Remove A/C electronic door actuator motor electrical connector from bracket on A/C evaporator housing.
  1. Remove three A/C electronic door actuator motor retaining screws.
  1. NOTE: The mounting bracket remains in place on the A/C evaporator housing.

    Lift A/C electronic door actuator motor vertically approximately 12mm (1/2 inch) to disengage it from bracket and actuator shaft, then pull A/C electronic door actuator motor back toward passenger compartment.

2001 Suzuki XL-7. Heater blows hot one side, cold the other.


No ductwork [to the lower vents] under the dash. They are part of the heater core / blower housing is integrated (all one piece).

After reviewing shop manual, we suspect that one of the three damper flaps is not positioning correctly; or debris has blocked one side (which makes more sense given the symptoms).

We're waiting for the temperatures to get back in the plus numbers to check out the physical arrangement.
