The problem concerning the no air flow out the defrost duct on my mom's 94 Toyota Camry is that the rod link from the electric actuator to the vent / defrost flap became disconnected way up under the center left side under the dash. I had to remove the lower air duct from under the steering column for access to use a 1 inch hole saw to make an access hole on the upper side of the case tube opening to see where the rod came off the lever. I went to the local Toyota dealer to try to buy a retainer clip but the part guy told me that it was only sold as a complete housing piece which was very expensive and involved removing a big portion of the dash pad assembly to replace the housing.
At this point , I plan on reconnecting the rod to the lever by simply installing a special washer style retainer on to the end of the rod to keep it connected. You might find a retainer like this one in a carberator repair kit.

. Air won't blow out of the floor or center vents just defrost ? Do you have manual or automatic climate control ?
Air Flow Control
Air flow control is accomplished in the following manner:
  • Primary control is through the function selector knob mounted on the A/C-heater function selector switch, which is part of the integrated control panel.
  • The function selector knob has the following positions: OFF, MAX A/C, A/C, PANEL, PANEL/FLOOR, FLOOR, FLOOR/DEFROST and DEFROST. The A/C-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 Vacuum Control Diagram , System Airflow Schematics and Vacuum Control Chart .
  • Two internal, single-pole electrical switches are also controlled by the A/C-heater function selector switch. The combination of these electrical switches controls the electrical supply to the A/C clutch and 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.
  • Vacuum Control Motors The vacuum control motors (18A318):
    • are located on the A/C evaporator housing, A/C recirculation air duct and heater air plenum chamber (18471).
    • direct system airflow to the vehicle interior as determined by the remote climate control module or manual override.
    • The five-passenger seating configuration has an additional vacuum control motor mounted on the heater air plenum chamber to control airflow to the rear seat A/C register (19893).

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).

When the engine is cold,check the coolant level.

Make sure it's on max.

A coolant system should be flush every two years.

If you did a coolant flush recently then air pocket can be the cause of the un-even heating problem.

The DIY method is to drive you car onto a ramp or a steep hill.

Iet the engine cool off and top off the coolant tank.

Set MAX heat + MAX fan

Let the engine ran for 20 minutes wih the cap off and the trap air will escape from the coolant reserve tank,

Check coolant level and top off coolant when the engine cools down.



A shop will charge $75+ for this but using an air operated excavate tool!

========

A car with over 90K miles may experience linkage problem to the heater control valve.

The heater control valve (near the firewall) may be stick over time.

Open the hood and move the heater to max and min. Back and forth.

Clean and lube the linkage with WD-40 to free the heater control valve.

If it's a vacuum type heater control valve then cash for leaky vac. hoses.


=======
Move the fan switch back and forth to re-new the electrical conductors.

Pass a vacuum over the control panel to prevent dust build up behind the console.

My 2003 pt airflow control knob does not shift air to pannel


something might be stuck in the ducting not allowing the door to move and direct air flow to the other ducts. First pull straight on the nob and pull it off of the dash. then take a pair of pliers and make sure the smell metal peg will rotate.

2007 F-150 Supercrew Lariat Cabin Air Filter


According to the shop manual you do not have one.
Air Distribution and Filtering adobe.gif Printable View (79 KB) NOTE: The air distribution system of this vehicle cannot be equipped with a cabin air filter.
There are 2 sources of air available to the air distribution system:
  • Outside air
  • Recirculated air
Recirculated air is automatically used when the electronic manual temperature control mode selector is set in the MAX A/C or OFF modes and can be selected in any mode other than MAX A/C, OFF or DEFROST by selecting the RECIRC button. Recirculated air is available in all modes except DEFROST. If the vehicle is equipped with an electronic automatic temperature control (EATC) system, recirculated air is used in OFF and is available in all modes except DEFROST. RECIRC mode is a timed function in FLOOR and FLOOR/DEFROST.
Air distribution within the vehicle is determined by the electronic manual temperature control (EMTC) function selector switch position, or is controlled by the EATC system in the AUTOMATIC mode. The air distribution mode on EATC vehicles may be overridden by the driver if desired. Air distribution doors are used to direct airflow within the heater core and evaporator core housing and the plenum chamber. An electronic mode door actuator is used to position these air distribution doors. One air inlet mode door is used to switch between FRESH or RECIRC air inlet. An electric actuator is used to position the air inlet mode door.
Air enters the passenger compartment from the:
  • instrument panel A/C registers.
  • heater outlet floor ducts.
  • windshield defroster duct.
  • side window demisters.
  • center flow-through console (if equipped).
Passenger compartment air is exhausted from the vehicle through open windows or body air vents.

Air won't switch to defrost vents


This system works with vacuum control doors. If you have a vacuum hose off under your hood it will cause this problem. Look on the passenger side near the evaporator - there should be a little round plastic bulb looking device - make sure it has vacuum to it. Also, check for other vacuum leaks in that area.

This is caused by a loose of vacuum to the mode control switch, the vacuum line runs through the firewall on the passenger side near the kick pad trim.
