Question about 2003 Mitsubishi Lancer

3 Answers

My lancer has AC issues. I start the vehicle, and the AC runs at a decently cool temperature for about 10 minutes, then I start getting warm air and a weird smell. It works better if I turn it to the highest speed, but the air comes out like it is on the first or second. I was told I have to refill my freon... any solutions?

The solution #1 posted will not work. My 2003 Lancer has the same issue. The gas has a full charge. The problem has something to do with the temp gauge on the compressor which shuts off the A/C. I haven't found a work around yet. Any ideas?

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.

Tip

Toyota Air Conditioners


This tip pertains to maximizing the cooling efficiency from your Toyota's Air Conditioning system.

(The info that follows is for vehicles that are not equipped with "Auto" AC.)

On really warm days, nothing is better than getting in a hot vehicle, and turning on the AC for a nice comfortable driving experience.

In our service facility, we continually see customers who are not totally satisfied with their AC output. Hopefully, this tip will address those issues, and just might be useful to you.

The number one reason for poor cooling with the AC on, is neglecting to select the "Recirculate" function on the heater/AC control panel.

What is Recirculate?
That mode is where the AC system 'recirculates' the air contained in the car, thru the AC box, over and over, until the desired temperature is reached. The Recirculate button, knob, lever or slide is easily identified by seeing a picture of a little car, with an arrow doing a 'U-Turn" inside the car. This is the opposite of the "Fresh" mode, which is an arrow going 'straight through' the little car icon.

If you are using the "Fresh" mode, you are actually admitting ambient air into the car. Ambient air is much warmer, and makes the AC work harder, and you will see a 10 degree rise in the air temperature from the dash vents. Also, some vehicles admit the 'Fresh' air from under the hood, so, leaving the 'Fresh' mode selected could actually draw in the much hotter underhood air into the AC system.

So, what to do? Anytime you use the AC, please verify that the Recirculate function has been selected. As stated above, this uses the air in the car over and over, and your cooling efficiency will be 10 degrees colder. You can easily check and verify this with an 'instant-read' thermometer. Put the thermometer in the center dash vent, start up the car, turn on the AC, select Recirculate, and watch the temperature drop. It should stop dropping around 34-36 degrees F (depending on humidity, sun load, and a few other things). Now, when the temperature is as low as it will reach, turn off the Recirculate device. You will see the temperature actually rise, maybe 10-12 degrees.

Some additional info: As long as the car is in Recirculate mode, the AC compressor will eventually turn off, when the interior makes the selected temperature. This saves you gas. If you run the AC with the fresh mode selected, the AC compressor runs all of the time. This wastes gas, and costs you more money.

The best way I can easily sum up Fresh versus Recirculate is this:

Running the car with 'Fresh' selected is like running your refrigerator with the door open. It works, but it does not work good. Choosing 'Recirculate' is like running the fridge with the door closed.
If this tip helps you, please leave a positive helpful rating. Thanks!

Hi i bought 2002 nissan sentra ..previous owner replaced head gasket ,water pump.thermostat ...car was running good for a week then sudeny no hot air inside(blows but cold) and 10 minutes later...


Thermostat is the wrong temperature range for the vehicle or it is installed backwards. It is opening too soon and not allowing the vehicle engine to come up to operating temperature soon enough. Have system checked, replace thermostat with correct temperature for vehicle

Car overheats and a/c starts blowing hot air when at a long stop light


It sounds like your cooling fan(s) are not working. Most vehicles run the cooling fan full time when the A/C is on so that air is always being drawn through the condenser. If the A/C is not on, then there is a coolant temperature sensor that should activate the fan(s) when the temperature reaches a specific temperature. It will cool down when the vehicle is in motion because the forward motion of the vehicle forces air through the condenser and radiator assemblies. You need to check the fans and the fan circuit for problems since they don't seem to be working in for either A/C or temp sensor.

What is the problem now? Please can you help?


If you turn on your AC on one day and nothing happens, you may be dealing with a major component failure. Your vehicle's AC system consists of a compressor, condenser, evaporator, expansion valve, a series of tubes and several fans/blowers. If either one of these components fails to do their job, it may result an entire system failure. For example, if the evaporator blower motor burns out, you will get little to no airflow through the vents.
Most modern vehicles also have safety mechanisms that may prevent a component from engaging if the pressure is low in the system due to a refrigerant leak. Refrigerant can leak for many reasons, including undone welds, loose connections, corrosion, physical damage from road debris, etc. Look for oily stains underneath your car, as they may indicate a leak. If you suspect a refrigerant leak, take your car to General Automotive. We will test the pressure and use special dyes to pinpoint the leak.
Warm Air is Coming Out Instead of Cold As you get in your car and turn on your AC, you probably expect it to be blowing hot air for the first minute or two until the system cycles through enough to cool it. But what if the air never gets cold ? Or maybe it it gets cooler, but not cold enough ? No, your car didn't get confused and turned on heat by accident. There is likely a problem with your condenser.
A condenser's job in a vehicle is to cool the warm refrigerant that was used to make the air cold in the evaporator. A condenser has coils and a fan to push the air through the coils and thus cool the refrigerant. If the condenser coils get dirty or clogged, or if the fan fails, the refrigerant won't be cooled completely, so the air will come out warm. It's best to take your vehicle to an experienced AC Repair professional to troubleshoot this problem if you don't know your way around under the hood.
Cold Air Blows Intermittently So you went for a road trip or a long drive, and after 30 minutes of driving realized that your AC suddenly stopped working or switched to blowing warm air. The cold air returns shortly, and the cycle repeats itself for as long as you are driving. What's wrong with your car?
Intermittent cooling is often caused by the components of your vehicle's AC system freezing up. Typically an iced over evaporator is the culprit. An evaporator covered in ice can't cool the air, so you would have to wait until the ice melts, which is why the cold air eventually returns. There may be numerous issues causing the icing-from a dirty cabin air filter to a blocked evaporator drain or an overcharged system. Look for puddles of water under your car-this could be a sign of a freezing problem.

Hi guys, i have mitsubishi lancer 2006 1.3 every time i start my car from cool engine, there a sound same as pouring water in my left dashboard near in steering and after a few second (around 10-30 sec)...


Hi,
I you believe the air trapped on your cooling system, just do this hints. Run your engine for awhile ( about 3-5 minutes) . then turn off your engine, open your radiator cap ( please wait foe awhile if it is too hot). Top up the coolant on your radiator. Repeat above step. It will be OK! now.

The heater blows out cold air only.


check the coolant level in the radiator it may be low
and starving the heater core

Impala has dual climate control. AC blows cold on


with a dual climate control system, it is imperative for a proper refrigerant charge to be maintained. the symptom you describe is a possible indicator of low charge on the system. the ac evaporator core is closest to the right side of vehicle thereby making air feel cooler on that side, on the left side of the vehicle the cooled air has farther to travel and warms up from cabin air before it discharged from the vents. this is the most probable issue for your vehicle...however if the charge is accurate, the issue would be more so in the air temperature doors which is located deep inside the dash...i hope this helps...good luck!
