SOURCE: hot air comes out of defrost vent at top dash and cold air out of

Hey, what setting is your A/C on Max AC? AC? Cycling air in vehicle or taking it from outside

The car icon on the right in this image is what I'm referring to when I say cycling air in vehicle.

Also, do you ever have cold air blowing? on any setting or any speed? if not, find your A/C fan, it is smaller the the engine cooling fan, sometimes there are 2 fans together. The AC fan should be located at the front of the vehicle and is usually electrically powered.

Also try to find your compressor, looks something like this:

is it running? is one pipe hot and one cold? (the pipes I am referring to are inlet and outlet pipes of the A/C compressor unit.)

Hope this helps, keep me posted

SOURCE: Air conditioning blows warm in hot temperatures

HAS THE COMPRESSOR CLUTCH CONTROL MODULE BEEN REPLACED? ANOTHER PROBLEM IS THE CLOSING COIL OF THE ELECTROMAGNETIC CLUTCH GOES OPEN IN HOT WEATHER, HAS THAT BEEN REPLACED.

SOURCE: 1986 Mercedes 300e The air conditioner vents blow

All the blend doors and vents are controlled by vauum. If you look in the rear firewall behind the brake master cylinder you will see a vacuum check valve with lines entering the cabin of the vehicle. The yellow colored ones are for your central locking,the green for a/c system, and red for your heater/water valve,clear for your source. Try isolating your vac. systems by unplugging lines and capping them off. Any leak in either system can adversly affect another system. So isolate your leak and then you will have to test your actuaters in the leaky system. If you unplug the red line and cap it off-the water will stop entering your heater core.

SOURCE: can't turn off EC on temperature control on a 1997

Press the O button to shut it off or any other button. Usually when the E/C sticks on its an A/C charge or sensor issue so check that also.

My heater does not work even if I increase the temperature, I do not know if the air con gas affect this since it is finished


the air con does nothing more than cool the air
if the temperature is not getting hotter then there is a problem in the heater system of the car
that could amount to blocked heater core , heater control not working ( module control) low coolant level, and air lock in the system or faulty thermostat stuck open

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.

I have a 2005 Lexus IS300 and I noticed water leaking on the passenger side every time I turn the heater on and it's only done this sence it started raining here in Oregon how do I fix this?its leaking...


Don't drive the vehicle in this condition. Interior water leaks can damage vital components such as the ECU.
Check the heater matrix, which is situated in the centre of the interior of the car, up behind the dashboard, roughly behind where the stereo is located. It is surrounded by block, plastic shields, which have to be removed to get to it.
If this heater matrix is leaking, then you will have to replace it ASAP, or otherwise risk overheating, or flooding expensive and critical components within the vehicle.

If it only leaks with the heater on and air-con off, then the heater matrix is your likely suspect.
If you have a leak with the air-con on only, then check your air-conditioning evaporator unit's drain pipe for security and for any blockages.

If your car has an air conditioner turn it on as well as the heater . Air conditioned air is very dry and usually defrosts the windscreen quickly. The heat from the heater will overcome the cold air from the air/con. It is good for the air/con to be run during the winter months as well as summer, it stops the seals drying out and leaking refrigerent.

WHY DOES MY RADIATOR FAN COMES ON ONLY WHEN MY AC IS ON ON MY 88 TOYOTA COROLLA


Hi,
it is generally because the air con heat exchanger has to be cooled in order for your air con to work correctly and cool the interior of your car.


The air conditioning utilises a gas by the name of freon. This gas is pumped around the air con system by a compressor. The gas, going through the aircon cooler or heat exchanger, starts to cool down. Depending on the system layout, the gas is forced through a very small aperture situated after the cooler. It reverts to a liquid, passes through the matrix in the car, a fan blows the interior air of the car through the matrix. The fluid picks up the heat, and cooler air exits the matrix and, (hopefully) cools the interior of the car. This endless cycle is repeated as long as the air con is powered on.

Hope this brief description will suffice.

2003 Jeep Cherokee (Liberty) air con


You most likely have a problem with a part called the air temperature control blend door, it controls the air flow across the AC core or heater core, it is most likely warped or the motor that operates it is defective or in most cases both are in need of replacing. This repair requires the entire dash be removed to access the AC parts.

1998 Honda Accord interior ventilation fan has stopped working.


they are right the air conditioner has nothing to do with the fan running .. your air conditioner is operated by a pressure switch .when it gets low on freon it will not come on, which saves your compressor. your fan only blows the cold air the air conditioner puts in to the coils located inside your dash. which the blower then blows the air into the car.. now you are on the right track look some more you will find the round motor under that dash near the glove box and its held in there with usually 4 small bolts. and removal is easy if you can locate it.. one wire and 4 small bolts and out it comes .. you should be able to get one at a local parts store ..
