Under the dashboard just above the gas pedal is the actuator rod to divert airflow from defrost to floor and vents. This may have come detached. move the wire/rod until it can be re-attached on the diverter door and wire-tie it on.

How to replace a 1999 toyota camry 4 cylinder heater core


Instructions
    • Drain the Camry's engine coolant, using a clean container for reuse. Disconnect the negative battery cable and wait a minute and a half for the airbag system to de-energize. Discharge and recover the air conditioner refrigerant.
    • 2Disconnect air conditioner suction hose and liquid pipe, then clamp on the tubes with an SST clamp. (Make sure you don't deform the tube). Disconnect the heater core hoses.

    • 3Disassemble every component of the dashboard, starting with the steering wheel and column. Removal includes the door scuff plates, cowl side trim, console panels and air bags. You'll need a second person's help to remove the dashboard from the interior.
    • 4Remove or disconnect all air ducts, the heater blower assembly, lower defroster nozzles, air conditioning radiator assembly. Remove the mode damper servo sub-assembly and Airmix damper servo sub-assembly, then remove the core from the air conditioner assembly.
    • 5Install the replacement heater core into air conditioner assembly. Reassemble all components of the heating/air conditioning unit, dashboard and dashboard components. Connect the heater core and A/C suction and pressure hoses, lubricating the O-rings with compressor oil.
    • 6Attach the negative battery cable, fill the cooling system and evacuate and recharge the air conditioner. Start up the engine and check for leaks in the system.

What to do when air conditioning vents on 2005 chevrolet silverado1500/v6 ?


It is all electronic these days an electric motor is controled by the selector on the dash. Remove the dash surround: gear selector in 1st engine off, tile steering wheel down, push down FIRMLY on the top of surround and pull towards you and off it comes. Remove the two screws that hold the heater/air cond. control in, there are 4 plastic clips as backup release them and gently remove the control, inspect for loose connectors (there are 2) it helps to run the blower to see if you have found the problem- I did.

2005 grand caravan front heater and defrorst not working ,rear heater is working . i also hear a hissing noice on the passenger side


Just a suspicion: hissing noise comes from failed/jammed/malfunctioning motor to move the door
in the ducting to route heated air to the hoses/ports for "heater" and "defrost."
Problem: failure of motor/linkage to heater/defrost selector door under the dash on the passenger side.
Also sounds like you have not blown fuse to this selector door.
Also - hissing noise could be air being forced against the closed door (which should be open) - in this
case, you'd want to check the fuse to the heater/defroster actuator door.
The rear heater works since its function is not related to the operation of the front heater/defroster.

Heat does not come out passenger side of the car but comes out drivers side


There is a blend door problem.

---
prev.gif next.gif HEATING AND AIR CONDITIONING Refer to Section 1 for discharging and charging of the air conditioning system. The heating system provides heating, ventilation and defrosting for the windshield and side windows. The heater core is a heat exchanger supplied with coolant from the engine cooling system. Temperature is controlled by the temperature valve which moves an air door that directs air flow through the heater core for more heat or bypasses the heater core for less heat. Vacuum actuators control the mode doors which direct air flow to the outlet ducts. The mode selector on the control panel directs engine vacuum to the actuators. The position of the mode doors determines whether air flows from the floor, panel, defrost or panel and defrost ducts (bi-level mode).

The Heater selector won't change from defrost to any other settings like floor heat or straight from the dash . the switch on the dash moves but the heat only comes from the defrost vents in the dashboard


hello, sounds like the cable broke or, lots of newer veichels use air lines, any way possible, check and see if air lines are still hooked up to the back of the heater controls, should be 4or 5 air lines together, all hook on one place behind heater controlls

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.


e72a310.gif

  • 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.
System uses a reheat method to provide conditioned air to the passenger compartment.
  • All airflow from the blower motor (18527) passes through the A/C evaporator housing .
  • Temperature is then regulated by reheating a portion of the air and blending it with the remaining cool air to the desired temperature.
  • 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.
