    I live in Alaska with my '01 Accent, and I have noticed that little to no air comes out of the windshield defogger, regardless of the control knob's position, or a selection of interior or exterior air. The only difference I notice is a faster accumulation of moisture and eventually frost, on the inside of the windshield when the 'interior recirculation' option is selected on the environmental controls.

    Does anyone know where I should start looking in order to solve this problem?

Inside cab blows out hot air controls are off but air still comes out


OUTSIDE AIR: Press this button to direct the system to use outside air.
Pressing the OUTSIDE AIR button will cancel the RECIRCULATION button.

RECIRCULATION: Press this button to limit the amount of outside air entering your vehicle.
This is helpful when you are trying to limit odors entering your vehicle or attempting to quickly cool down the interior. Pressing RECIRCULATION will recirculate air continuously.

RECIRCULATION is used when the fan control is OFF to limit odors, outside air and dust from entering your vehicle. All button lights will go off. The last setting selected will activate when the blower is turned back on.
Pressing the RECIRCULATION button will cancel the OUTSIDE AIR button. To return to normal operation and to prevent stale air, be sure to return the OUTSIDE AIR.

Between HEATER and BLEND mode, outside air is forced to reduce window fogging. If the RECIRCULATION button is pressed, the LED indicator will flash three times indicating that forced outside air is activated and RECIRCULATION is not available.

I think what your experiencing is normal. If you want to keep cold air form coming into the cabin, press the recirc button.

I hope this helped, icon_e_biggrin.gif

Tip

Tips for operating Air conditioning system on Toyota Hilux and someother...


To cool off your Toyota after it has been parked in the hot sun, drive with the windows open for a few minutes. This vents the hot air, allowing the air conditioning to cool the interior more quickly.

Make sure the air intake grilles in front of the windshield are not blocked (by leaves or snow, for example).

On humid, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

Keep the area under the front seats clear to allow air to circulate throughout the vehicle.

On cold days, set the fan speed to high for a minute to help clear the intake ducts of snow or moisture. This can reduce the amount of fogging on the windows.

When driving on dusty roads, close all windows. If dust thrown up b the vehicle is still drawn into the vehicle after closing the windows, it is recommended that the in intake be set to FRESH and the fan speed to any setting except "OFF".

If following another vehicle on a dusty road, or driving in windy and dusty conditions, it is recommended that the air intake be temporarily set to RECIRCULATE, which will close off the outside passage and prevent outside air and dust from entering the vehicle interior.

HEATING

For best results, set controls to;
Fan speed ---- Any setting except "OFF"
Temperature----Towards WARM (red zone)
Air intake ---- FRESH (outside air)
Air flow ---- FLOOR
Air conditioning ---- OFF

For quick heating, select recirculated air for a few minutes. To keep the windows from fogging, select fresh after the vehicle has been warmed.

Press the "A/C" button on for dehumidified heating.

Choose floor/windshield air flow to heat the voltage interior while defrosting or defogging the windshield.

AIR CONDITIONING

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

For quick cooling, move the air intake selector to recirculate for a few minutes.

VENTILATION

For best results, set controls to;

Fan speed --- Any setting except 'OFF"
Temperature --- Towards COLD (blue zone)
Air intake --- (outside air)
Air flow --- PANEL
Air conditioning --- ON

DEFOGGING

The inside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone) to heat; COLD (blue zone) to cool
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- ON

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

On humid days, do not blow cold air on the windshield. The windshield could fog up because of the difference in air temperature on the inside and outside of the windshield.

DEFROSTING

The outside of the windshield

For best results, set controls to:

Fan speed --- Any setting except 'OFF"
Temperature --- Towards WARM (red zone)
Air intake --- FRESH (outside air)
Air flow --- WINDSHIELD
Air conditioning --- OFF

To heat the vehicle interior while defrosting the windshield, choose floor/windshield air flow.

AC recirculation is not working (outside temp is -37 degree centiigrade).


there is a damper that opens and closes to allow air to recirculate or come from outside. Find out where that is and check it out.

What exactly does max a/c and norm a/c do; the difference, and performance? What does recirc do and why is it available during max, norm, and bilev but not during defrost? The same a/c properties are...


Hello: Max cooling is when the recirculate door opens. With the recirculate door open, 80% of the air flow comes from inside of the car and 20% is outside air. That makes the cooling more efficient. Normal a/c operation is 100% of airflow comes from the outside. These settings have nothing to do with compressor operation. Also Decreasing or increasing the amount of cooling has nothing to do with compressor operation, what that does is control the amount of air going from the evaporator core either through or past the heater core. The a/c compressor runs the same amount of time regardless of settings on the control panel. Also in cool weather the compressor runs in the defrost mode to keep the windows from fogging up. None of these settings affect performance, the only time performance is affected is wide open throttle (WOT) in that mode the engine computer shuts off the compressor to allow max power of the engine, ie: passing gear.. When A/C is selected the compressor is on, none of the settings will affect gas mileage, ie, low/high, max/normal 60 degree or 90 degree.

Why my window is fogging whe i turn the heater ?? i recently bought my toyota carina 3 model 1994 but the window is fogging , what should i do?


Make sure the vent system is set to draw air from outside. If it is set to recirculate the same air that's inside the vehicle without drawing fresh air from outside, the resulting humidity that builds up inside the vehicle can fog the windows even when you run the defrost. You can also try opening the windows a bit to get some more air moving inside.
If it still fogs when the vents are set properly, you may have a leaky heater core. The heater core is a small radiator that is located under the dash that the heater system blows air through to heat the inside of your car and provide heat to defrost the windshield. The fog may be coming from the heater core leaking hot coolant steam that's being circulated through the defrost system. If this is so, you will need to replace the heater core.

Will not defrost , interior is humid(has heat), but when car shuts off interior windows freeze and must scrap ice off inside glass to see. problem is accumulative....more we drive the worse it gets


Could a symptom of 3 or more problems: (1) Sounds like you have got the cabin air intake set to "recirculate" air from within the cabin. Once the car is warmed up in cold weather you need to move the cabin air intake control so that it draws air in from outside the vehicle. Having the air intake set to "recirculate" with the windows closed means that the occupants' breath causes the windows to mist up - this gets worse the longer the car is driven, and this is exactly the problem you're experiencing. (2) If, however, the air intake is actually set correctly, then the air vents would appear to be blocked, either with debris such as leaves, or snow or ice (this would have the same effect as having the heating controls set to recirculate cabin air. (3) There is a possibility that the cabin air filter (if one is fitted) is blocked - replacement or removal should solve the problem.

Bad evap sensor


this is covered by your warranty for 36/36. The sensor is usually on the evaporator inside the plenum case under the dash. If the eavp drops below 32 degrees F, then ice starts to accumulate on the fins of the evaporator, and eventualy blocks the flow of air through it. You will hear the blower running, but no air coming out.
To reduce liklihood of icing, always put a/c in "recirc" mode. This recirculates the already cooled and dehumidified air back through the a/c system, therefore reducing humid air icing.
Note: never use recirc in winter because you will fog up the windows.

My 1999 Malibu has had ice on the inside windows and windshield during these freezing temps. before the really cold weather they steamed up on the inside? This did not happen last winter?


This could be caused by a leak in your heater core,,do you notice the steaming up more on the passenger side,,then it will most likely be the heater core which is leaking coolant into the car.

A/C air flow problem


AC works as so..

It does not actually cool the air, however it removes the heat from it (and without heat the air feels cool). As the air is blown around the car the AC system removes the heat from the air, and then it moves it to the condenser at the front of the car (infront of the radiator).

Now usually the car is moving forward, so that air flow will cool the condenser and then you can move more heat from the air inside the car and push it out the front of the car again. This is why, if you have a front wheel drive car, you will hear the cars fan start as soon as you turn the AC on.

Also the car will be much better at cooling the air that is recirculating inside the car (your a/c system will have a button for this) then if it tries to cool hot air from outside.

The long and short of it is that if you hop in a hot car, start the car and run the ac (even at full) it wont be cool straight away, it is mostly influenced by how much you are driving forward.

Try this. Start the car, turn the AC to recirculate the air, turn the AC on and go for a drive for 10 mins, pull over and wind down the window. Compare the outside air to the inside air, then you will see the difference.
