Hi,

Please pardon my english, I am french and it isn't perfect. :(

I have a new kia cee'd 1.6Gdi DCT6 full options and the AC Unit has an erratic behaviour.

The system blows fresh air when the outside temperature is between 15° and 18°c and when I choose a temperature setting that is less than 24°c on my climate control (A/C off, no dual, automatic ON).

I think it's abnormal, would you have a solution to that rather annoying behaviour? Thank you very much in advance for your reply.


Best regards,

Don't worry.

I have an early Ceed with climate control which I constantly have battles with, although I would have hoped the newer one is better.

The problem with mine is different. When the outside temperature is 6-16 it produces too much heat even when turned down to 15.5. I would be happy to swap the faults in my system with yours!

If you have a thermometer and measure the cabin temperature it might be correct. During daytime a lot of heat enters through the glass so the system is choosing to only deliver a small amount of heat through the ventilators. Because the air is moving and it is ony a small increase in temperature it can feel cold. At night, you might find it behaves differently.

If you like, I can try to explain further and show a graph of my measurements of the behaviour of the system.

No problems on my New Ceed 2 1.6 diesel auto with the heating or A/c which are excellent so far. However if you require a fully auto box at all times avoid the Ceed 3 with DCT box and many useless annoying features.

Yet another thread hijack! What does the DCT box have to do with heating?????

Keep it on topic!!!!!!!

Can anybody actually help Lex, or advice him to visit the Kia dealer to have system checked or repaired please?
Talking about blah blah going off topic, is still off topic!

However I agree, Db please stop bring other unrelated faults into your posts. You are not helping.

Our is a MY 2011 3 with climate thus should be similar to your system in operation. We have found the system very easy to use and very good at keeping the interior at a satisfactory temperature without needing to adjust the temp setting. For example, during the heatwave in May we set off on a journey with an outside temp of 16 degrees and set the interior temp to 15.5 degrees as we normally do on a warm day with the A/C off, you don't need to cool the outside air if its already similar to the temp you want inside. When the outside temp warmed up we switched the A/C on and set the temp to 20 degrees, by the time we arrive home several hours later it was 28 degreees outside but we did not adjust the temp again, brilliant.

One piece of advice but this might not relate to yours since its a differnet model, do not use the auto button, its useless. All it does is decide where to blow the air and at what fan speed. I can decide that, if my feet are hot I cool my feet, if the head is hot I cool my head, if I need the air to flow faster I speed the fan up. How can the system know where I want the airflow, forget that garbage button and its a great system

The system in my car is obviously not broken but not broken is not the only requirement needed to maintain comfort. Also what is comfortable for one person isn't necessarily satisfactory to another.

Lex wants to know whether it might have a fault before a possibly wasted trip to dealer. From the description given I would suggest it probably isn't faulty but as the subject interests me I am open to more discussion.

These are some steps you can try and may or may not work. Kia user manuals are not always correct so for my car, it was the last sequence that worked.



1. Turn the ignition switch to ON position.
2. Select the defroster position pressing the front defroster button
3. While pressing the air conditioning button (A/C), press the air intake control button (recirculated air position) at least 5 times within 3 seconds.

The A/C display blinks 3 times with 0.5 second of interval. It indicates that the defoggin logic is canceled or returned to the programmed status.

For manual climate control system:
1. Turn the ignition switch to ON position.
2. Turn the mode selection knob to the defrost position.
3. Push the air intake control button at least 5 times within 3 seconds.

The indicator light in the air intake control button will blink 3 times with 0.5 second of interval. It indicates that the defogging logic is canceled or returned to the programmed status.

To cancel the auto defogging logic system:

1) press the front defroster button 4 times within 2 seconds while pressing the AUTO button.

The indicator will blink 3 times to notify you that the defog logic system
is cancelled.

With all respect, I don't think the original questioner has a problem with the defogging.

If you read carefully, I mentioned the manuals are wrong, and pressing one of the key sequences would most likely assist the OP in obtaining more control of the entire system - not just auto defog logic

The manual makes no mention of anything other than the defog logic for a manual system. If you know of other adjustments - particularly applicable to the automatic system - it would be interesting to know what they are.

Hi,

Thank you for your answers. For 3 days, I'm doing many tests for to better understand erratic behaviour. ;)

Have you got a manual for a new model Ceed. I am sure the Ceed is not sold in the states. There is no point telling the OP what to do based on a car that is different to yours. Suggest you let the EU based members help.

It appears many Kia manuals got the hvac instructions wrong in terms of correcting 'erratic behavior' (which I can agree with somewhat)

The key sequence for many kia hvac systems are the same or similar setup.

By trying one of a possible two or three ways (which would do NO HARM other than reset the system) the op might find the solution as there were no other bright ideas being dispensed (other than useless criticisms)

So much for vote of confidence.

What happens if forum users try one of these supposed fixes for another car from another country and it causes expensive problems that are not covered by the warranty. Who will pay the bill.

Best let the dealer explain how the system works if you cannot understand the manual or simply let the dealer fix it if its broken.
