Question about 2000 Hyundai Elantra

1 Answer

Air Conditioning Not Cold!

My Air Conditioning was barely cold last summer.
I had to keep it on Max on Hot Days and wait almost 20 minutes before it got comfortable.
Is this normal?
Can I do anything?

Get someone to re-gas it with a dye and see if it's leaking. Check the compressor.

2000 caddy Seville ...after starting and engine warm turn on the heater and it blows cold air. Fan works / waiting for hot air and then all the sudden it kicks in. Engine at normal temp


Low coolant, if there is an air pocket in the engine it will make it to the heater core. Once there , the air coming out is cold/cool. Once the coolant fills the heater core, it gets hot. If the coolant is fine hot or cold, then have the HVAC system scanned.

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.

Rear air conditioning blowing hot air


I suggest that you take the Vehicle to a Reputable A/c Repairer, NOT a Muppet Shop, as I call them occassionally.
Request a CHECK and ADVISE ONLY. on the system. This will determine the exact fault[s] in the system.
From you comments, I would expect to find a Reducing Freon flow, through a probable Expansion valve failing.
Then you can decide, if on nearing the end of the HOT period, having the Diagnostic done, is the expense justified now, or can it wait until later.

?mitsubishi Eclipse 2003 ac


If you overcharged your ac, it will not get cold. It should take about a can and 3/4 max. Do this first, it probably has too much air in it. Since you don't have a vacuum pump, let some of the gas on the low side. You will feel the air coming out is not cold, but keep releasing until the gas coming out is cold. Now you have taken most of the air out. The gauge should be no more than between the blue and the yellow. If the low side gauge remain high, then you probably have a bad expansion valve.

Ford ka heater blows hot air all the time


Your problem is a faulty heater control valve. The design used on these vehicles allows for hot water to flow constantly and compete with the evaporator as there is no blender door. You have to replace the valve and possibly the control head. Meanwhile, you can bypass the valve to have cold air
