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.

The air conditioner on our 2007 Dodge Ram 1500 hemi will not cool the cab when it gets above 70 degrees. There is freon in the system air cold. It's impossible to use in the summer. Any suggestions?

close off the cab circulation to the outside air
make sure that the condenser fan is fully operational
fan in front of the radiator
have an accredited ac specialist check the gas pressures are correct --if there is excessive gas the high pressure switch will shut the ac compressor down
shut off the heater system as it it is a climate control system , there may be still hot air mixing with the ac air

P1450 code came on after first really cold night.

  • P1450 Error Code Excessive Fuel tank Vacuum
If this only happens once from a moderate temperature day to a dramatic cool down overnight it could make sense.
When fuel cools the vapor condenses creating a vacuum in the tank. A working evap system should restore pressure eliminating excessive vacuum.

My a/c is working but compressor is not working.

this will be from the head pressure being excessive as the gas is not being converted to liquid in the condenser. The main reason being that there is insufficient air passing through the condenser from the ac fan not working. There has to be an extra fan in front of the condenser to maintain air flow at all times the ac is operating. The second reason is excessive amount of gas in the system. Have the pressures checked by an accredited ac shop.

Fogged up windows

Are you using the fresh air option ?
If you are, you could have excessive moisture inside the cabin. Running the hvac on defrost should kick on the ac compressor and bring in fresh air too.

Window fogging

If it were a leaking heater core, the inside glass surface would have an oily film along with the fog.
It sounds like your fresh air intake is not working. You have to get fresh air from the outside to be able to get rid of the excess moisture inside the cabin. Or you have excessive moisture inside from a water leak that the system can't overcome.

Coolant leak but no sign of leak

Do your windows fog up when you use defroster? Any residue on the inside of winshield? Is the carpet damp under either floor mat? These are signs of a leaking heater core. If no to all of these check at tail pipe when running for excessive water (depending on the climate if it's cold out of coarse there will be some condensation) if so does is leave a residue on your hand? This could be the sign of a blown head gasket, blown intake gasket or cracked head. I don't know what engine you have but, Chevy 3.4 engines are known to blow intake gaskets.

Excessive exhaust when cold

Its cold! is it like polluting excessive? If the exhaust smoke is white its normal especially on a older car. Have you ever gone outside in real cold weather and when you breathe you can see the steam pretty much same thing. As long as the car is running the same then its more likely to be from the cold. Good idea may be to let your car thoroughly warm up before you drive off in cold weather.

Power cuts when i turn key

If you mean everything goes out when you turn the key to the START position, understand this:

* Accessories will turn off during START to remove excess load on battery

* A weak battery will draw down and cause this symptom - the two most likely times of year are when it first gets really warn outside (batteries hate heat) and when it gets really cold outside (Natteries hate cold).

* A defective starter can draw excessive current and cause this symptom.

If your battery is more than three years old, I would suspect it first..

I have a 2003 Mitsubishi Eclipse. The A/C condensates inside the vehicle on the drivers side. I have located the drain tube and it is NOT plugged up. Is there any other reason why it would do this?

The most likely cause would be that you have the a/c set to let in outside air as opposed to recycling inside air. If the system is set to recycle, the moisture in the cabin air would quickly be removed, but set to outside air (or if the windows are open) the humidity would stay at a high level, causing excessive moisture to be collected on the evap coil. Are you confident that you located the a/c drain line and not the drain from the cowling? Hope this helps! Dano
