Question about 2002 Jaguar X-Type

Excessive condensation on all windows, have to use defrost on high at all times

Whenever it is cold outside my car has excessive condensation on all windows. I have checked to make sure it is not recirculating air. The only way to clear even the windshield is to run the defrost at high heat. I believe there is a clogged drain tube because in the summer there is no water draining when the air conditioner is on, but no one seems to know the location of the drain.

    I have the same problem. I've had the heater core and A/C units checked out by my local Jaguar dealer, and I've also had a new A/C control module put in. All of that and I still have defrost problems. They said they checked all of the hoses and the drain and all looks ok. The mechanics are sick of hearing from me and now treat me like I'm insane because it "all checks out" and "shouldn't happen". Nobody seems to know what the problem could be, but it gets so bad in the winter that I literally have to keep a scraper and rag handy so I can clear the windows. There is no problem with the heat, as it gets very warm in my car. My windshield stays clear, but I believe its because the air is constantly blowing across it keeping it dry. However, all of the other windows in the car have either frost or condensation/fog on them.



    Anybody have the same problem? I love this car, but this is too much and makes it completely unpractical and non-functional to drive in the winter. What could be causing this to happen?

    This all sounds so familiar - great car, but it is horrible in the winter! My wife is ready to sell it! I would love to know where the drain tube is as well!

    same problem, the heat is not the problem but I need to scrape the inside of the windows to see outside. I have opened the back of the sunroof and that seemed to kinda work for a while.

    My wife has the same problem with her car. We had it into the dealer and they changed a filter and fixed or replaced a flap/closure on the recirulation tubing. This fixed the problem last winter, but it is back again this winter. Ready to sell the car as when it is cold out you cannot see out anything but the windshield so makes driving tough and dangerous.

    I am having the same problem with the frost building up inside my car as well. I have a 2002 X-type and this just started happening last week. If my car is sitting it will eventually clears all the windows; however once I start driving all my windows fog up. I think I know what the problem is with my car the back vents are not working as I don't feel any air coming out of them. I going to see if maybe the spark plug went as the air works fine in all my other vents. Well cross my fingers...just too much to take it in to the dealer.

I have the same problem and this was due to the air supply under the bonnet of the car. You have to release the plasticcover just below the screenwipers pull out the airfilter (it is a bit narrow so be carefull with your hand). Behind the airfilter there is a flap. In my case this flap is down, which cloes the airstream. OPen this flap by moving it upwards and lock it there with tape or something and the problem is solved. The only thing is that you can not close the air inlet with the button on your dashboard, but at least the major problem is solved.

I have the same fogging problem and after 3 attempts by our local dealer I took it to my local mechanic. He found somewhere on the internet that there is a "mixing box" under the dash that has small air vent motors that were said to be the issue. Has anyone repaired this item and did it fix the fogging?

    My 2002 X-Type has the same problem and the issue IS the blend door actuator. Unfortunately because of the location of the blend door it is an 8 hour repair job. I opted not to spend the $800 dollars to get it fixed and instead vent the sunroof or side windows. However, I did a lot of research and this broken blend door is absolutely the cause of the problem.

Ask dealer/service person for location of drain. Many times this is on the engine firewall even with lower part of heater.AC housing. Also if car was undercoated this drain may be covered over.

Why does my kia picanto 2013 windscreen totally mist up and will only clear when i put ac on hwen it clears i turn ac off then within seconds it mists up again


the windscreen fog is from humid air coming in from the outside
air conditioners work by removing the humidity from the air so if you close of the outside vent then the recirculated air inside the cabin eventually has all the moisture removed
that is why the windscreen clears because there is no moist air to condense on the cold windscreen
now you will say that it is too cold and that is why you turn it off
well try this -- leave the ac on and adjust the heater control to produce lukewarm air no fogging up and not cold
it is called climate control

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.

When it is cold outside, why won't the heater defrost the windshield without opening the window a little and letting cold air into the car?


This because with the windows closed, you are in a sealed enclosure and you are pulling air from outside and putting the vehicle under pressure. Imagine blowing into a partially inflated balloon without having your lips on the balloon. The pressure restricts the air flow. If you want to keep the windows closed, you should choose the Recirculated Air setting which takes air from INSIDE the car and circles it over the windshield and back into the car.

How do I stop the inside of windows from fogging up


You need to switch your air flow from recirculate...to out side input...the recirculate always fogs up when cold or wet outside...Hope this helps. Use the defrost mode...but be sure recirculate is off...

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

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.

2008 vw jetta makes noise from blower


OK. The noise you are hearing is the recirculation flap motor. It could be what is causing the condensation. Easy way to check in after the noise has stopped push the recirculation button on the AC controls to see if the noise happens. If the motor is bad and the flap isn't closing you could be getting moisture from the outside air. As far as the check engine light goes there is no relation. 2 completely different systems. The flap motor would probably run you a couple hundred of dollars. The check engine light could be anything.

My Audi 2005 Air con system will not blow cold air is this anything to do with the vent at the front of the vehicle that creates an airflow


Well, I don't know. I would have to see the car.
Generally, as long as air can flow thru the condenser and radiator, the ac system can produce cold air.
As for the interior, you normally pull in outside air and cool or heat it, but you can also recirculate inside air which would close off the outside fresh air intake for the cabin.

How do i fix heater core on a 2006 chrysler 300


If you're getting hot air, it's not the heater core.

Windows fog up because the humidity level inside the vehicle increases while the temperature of the windows decreases to a point where the dew point of the air is higher than the temperature of the glass. When this happens, moisture from the air condenses onto the glass. When you breath out, you increase the humidity of the air in the car because of the moisture in your breath.

The key for defrost to work isn't necessarily heat, it's more important to dry the air. There are two ways of doing this:

1.) Make sure you have the air recirculation turned off. This feature causes your car to recirculate air from inside the car through the air ducts. In the summer when it's hot and humid outside, this is what you want. However in the winter when the air is dry, you want to bringing fresh dry air from outside to replace the humid air inside the car.

2.) Turn on the A/C compressor. This will cool the air before it passes through the heater core. Cooling air removes moisture. This is why your car drips water from underneath in the summertime when you run the A/C. It is literally removing moisture from the air.

However, if your heater isn't working (blowing cold air even when on the warmest setting), then you may have a different problem.
