You can get it from either the mfr or a local appliance part store. The value of a parts store is that you can get it right the first time.

We just bought a 2004 Buick Rainier. Drivers side air controls work great. Passenger side is only blowing cold air even when it's set on 90 degrees. What could the problem be?


Do you have manual or automatic ? It's probably the Air Temperature Actuator - It's an electric motor inside the heater/A/C unit that controls a door that diverts air over the heater core or A/C evaporator . The HVAC - heating , ventilation , air con ,control module has the capability to set an store DTC'S - diagnostic trouble codes . Could have one or two of those stored in the control module . You would need to take your vehicle to the dealer or some other qualified repair shop that has diagnostic scanner that can check for these type codes . These codes will not turn the check engine light .on. Different system .
?€¢
B0414 is for the left air temperature actuator.


?€¢
B0424 is for the right air temperature actuator.


The HVAC control module controls the HVAC door actuators to regulate the airflow through the HVAC system. Each actuator consists of a stepper motor, a logic circuit, and a potentiometer. The potentiometer inside the door actuator allows the module to monitor the current position of the actuator drive shaft. The module supplies a 5 volt source voltage to the potentiometer on the 5 volt reference circuit. The module supplies ground to the potentiometer through the low reference circuit. The HVAC control module monitors the voltage drop across the potentiometer on the door position signal circuit. When the actuator shaft rotates, the voltage on the door position signal circuit changes. The module converts the voltage value to a count value where 1 volt is approximately equal to 51 counts.
The HVAC control module calibrates the travel range of the HVAC door actuators when it is initially powered by the battery positive voltage circuit. During calibration, the module commands the actuators in each direction until door travel is stopped. The module stores the minimum door positions and the maximum door positions of each actuator into memory. The total travel range is calculated by subtracting the minimum door position from the maximum door position. The door actuators can be calibrated again with a scan tool.
?€¢
B0408 is for the left air temperature actuator.


?€¢
B0418 is for the right air temperature actuator.


Your best bet is to take to a repair shop , the dash (instrument panel ) has to be taken out ( apart) .

No heat. New thermastat, heater core flushed, good circulation. Has a rear heater.


Does blower motor work , air blowing out of ducts ?
Temperature blending is varied by the air temperature control door, which regulates the amount of air that flows through and/or around the heater core (18476) , where it is then mixed and distributed.
Movement of the control knob from COOL (Blue) to WARM (Red) causes a corresponding movement on the air temperature control door and determines the temperature that the system will maintain.
Temperature Control
The temperature control operates in the following manner:
  • Temperature control of the heater system is determined by the position of the temperature control knob (between COOL-BLUE and WARM-RED) of the heater control .
  • This control knob is connected to a potentiometer mounted in the heater control . This potentiometer is electrically connected to the electric blend door actuator that operates the A/C air temperature control door.

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.

Melnor 4 zone aqua timer dosent follow program


Water timers and Melnor timers last a year or two. They come with 1 year warranty for defects in workmanship.
Change batteries, reset timer if there is a reset protocol, buy another timer. Melnor, Orbit, are major brands. Gardena is not supported. Yardworks repackages other brands.
Copy following link for all watering and irrigation timers on market, with links to manuals for each brand:

How to set time on Yardworks two zone water timer


Copy following link to access manuals for each brand of water timer on market 2013:
http://waterheatertimer.org/Woods-timers-and-manuals.html#sprinkler
Yardworks does not have website, manuals or warranty claim procedure.
Instead, yardworks repackages other brands of timer, generally water timers, such as orbit or melnor and raindrip. And sometimes repackages other brands of outdoor timers.
Recommend folks stay away from timer-repackagers such as Yardworks, Timex, First Alert, and buy brand names that have clear customer resources.

My air conditioner is working but won't blow out


Are you saying the temp blend door is not working?
If yes, it's the control head or the temp blend door motor on th plenum case under the dash. Buy used on ebay.

DO you have manaul or electroic controls?

If electronic

A/C Electronic Blend Door Actuator The A/C electronic blend door actuator is located on top of the A/C evaporator core housing (19A553) assembly.
  • Its function is to move the A/C air temperature control door on command from the control assembly.
  • The A/C electronic blend door actuator contains a reversible electric motor and a potentiometer. The potentiometer wiper 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.
  • A five volt signal is applied to the ends of the potentiometer. The voltage available at the wiper indicates the position of the potentiometer. The expressed value of the actuator wiper voltage is sent to the control module and matched with the wiper voltage of the module potentiometer. The printed circuit board then drives the actuator motor in whichever direction is necessary to make the actuator wiper voltage agree with the control module wiper voltage.

Blend door for front temp control is stuck in the 'cold' position this winter. Is there a way to manually move and fix the door to get some heat?


you have to replace the blend (heat/cold) door motor, you can try to remove motor and turn door and try to jam something in door handle slot ,that the part that the motor turns,hope this helps.

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.

I have the same problem with my windstar blower is fine but is coming cold air but no heat i dont know what to do can any one show me how to fix it thnx


First, feel the heater hoses going into the firewall under the hood. If they are hot, then you have hot engine coolant going into the heater core. If they are not hot, then you either have a bad thermostat or you are very low on engine coolant.

Next you need air flowing through the heater core so it can come out heated through your vents. If the iar is flowing somewhere else, your temp blend door is not moving because the bend door motor is bad or your temp knob on your heater controls is bad. The blend door motor is an electric motor.

------------------------------------------------
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.
Temperature Control
The temperature control operates in the following manner:
  • Temperature control of the heater system is determined by the position of the temperature control knob (between COOL-BLUE and WARM-RED) of the heater control .
  • This control knob is connected to a potentiometer mounted in the heater control . This potentiometer is electrically connected to the electric blend door actuator that operates the A/C air temperature control door.
