Question about 1992 Toyota Camry V6

Open Question

Stripped gear on heater temp selector knob

I have a 1992 camry with a climate control module that is all controlled with knobs. The left most knob controls the heater tempurature. This module has the gear stripped in it so the lever on the bottom of it will not move to open the vent or the hot water valve. I need to take this unit out. I easily remove the cable from it that goes to the air deflector but I am having a hard time getting the one that goes to the heater valve (the right most or one closest to the pivoit point) out. Do I just pull it very hard out of the crevice that it is pressed into? or is there a trick to this. This whole issue is not discussed in my manual, it is pretty skimpy on the heater system details.

SOURCE: The knob that controls the doors to the HVAC vents is stuck

TRY CAREFULLY DISCONECT THE CABLE AT THE BLEND DOOR AND 1. TRY WORKING THE KNOB,
IF WILL NOT MOVE YOU NEED A NEW CABLE.
.2 GENTLY TRY MOVING THE BLEND DOOR BY HAND. THIS SHOULD GIVE YOU THE DEFROST FOR NOW. IF IT WON'T MOVE YOU SHOULD TAKE IT TO A GOOD SHOP THERE ARE A LOT OF SMALL AND EASLY BROKEN PARTS IN THE HEATER BOX. A DAMAGED BEND DOOR ALLWAYS RUINS THE CABLE SO IT WOULD NEED TO BE REPLACE TOO.

The heater is controlled by that valve - you don't get heat because that valve isn't opened. Take the control cable out of it and try to open the valve.
If it opens and the water flows freely then the problem is in the dash controls unit - more precisely in the rotary temp button (where that cable goes).
If you can't open it then it's clogged and must be 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 !

Passenger side knobs not working on climate control unit


All 3 are possible problems. A fuse is most likely the problem unless something got spilled leaked its way into the unit. Check all the fuses with a test light first before you try and replace the unit

No heat / heater not working


not blowing air or when switch is on blows cold air when you have climate control knob turned over to heat? it could be a switch or blower motor or fuse if its not blowing any air. if its blows cold air when knob is on heat then is can be thermostat or low on coolant or it could be climate control module or it could be a air filter in dash.

My blower only blows threw the defrost vents. all climates everything, no matter where i put the control knob. dealership says the solenoid got stuck closed after using my 4 wheel drive.


Assuming you have vacuum controls at the heater control head, you have a classic vacuum leak in the hose from the engine intake manifuold to the control head, or the vaccum storage canister somewhere in the engine compartment. It is required to fail to defrost by law.

Climate Control Assembly
The climate control assembly has 3 system controls:
  • The function selector switch combines a vacuum selector valve with 2 electrical switches to supply battery positive voltage (B+) to the blower motor control circuit and the A/C clutch circuit (if equipped).
Vacuum Control Motors
The 2 vacuum control motors:
  • are actuated by vacuum from the function selector switch.
  • position the plenum doors to direct system airflow to the vehicle's interior as determined by the function selector switch setting.
The vacuum reservoir is behind the driver fender well, black plastic ball.

If you have diesel, then you will have a vacuum motor under the hood.

please rate if this helps.

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 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.

  • 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.
