Just got a fully load 07 Sonata. I cannot confirm this due to weather is still cool. I pushed the "AUTO" round knob to run automatic climate control. Does the LCD show AC or the AC button lit when the system decided to run the AC. How to tell the AC is on? In manual mode, AC comes on if temperature dial is cranked below 17C (I think ?) or by pressing the AC button; in both cases, the LCD show "AC".

You will see that it pulls moisture out of the cabin so no fogging of the windows. 2. Push the AC button and the AUTO is off and your AC is on and temp. is controlled in the same manner as above. 3. Push AC button and it will turn off completely and your compressor will NOT be on. It's a little crazy but that's the way it is set up to work. I'm used to it and it works the same way in my 06 Azera Limited. In the summer here in NY I keep it on AUTO all the time and the compressor will cycle and keep the air comfortable and at the same temperature. Hope this explains it and that it makes sense. Good luck with your Sonata. It's a really neat car.  Don

I pressed some buttons today and the behavior is now as expected. Too bad I forget what I pressed to get into this behavior and worst forget the steps to fixed it

Replying to: targettuning (May 15, 2007 6:37 am) I have a habit to switch off AC and let the fan run a minute prior park to remove some moisture on the condenser. This is way too complicate for the wife to follow when in auto mode. I think something is missing in the climate control software. Everything on the climate system in auto mode have an indicator, except AC in auto mode. Ideally the AC indicator should follow the compressor relay in any mode. Interesting question: #1 The climate system doesn’t have a heat only or cool only switch in auto mode, in the event that the setpoint temperature is met, what does the climate system do, for example in summer ? I can think of two scenario. a) Switch off AC, keep fan running; temperature buildup then switch on AC. b) Switch off AC, keep fan running, turn on heater; temperature buildup then switch off heater and switch on AC. I hope this is not the case! #2 The same question for winter. #3 How does the logic work when ambient is at the borderline like in fall and spring.

i need help with my A/C. I recently changed the compressor because it stopped working and i went to a mechanic who found there was a leak in the compressor. but after the replacement i found the A/C is not as cold as before by saying that i mean i dont feel cold air but kind of "cool" air instead. I went back to the mechanic again thinking maybe there was not enough freon. And they checked and recharged the A/C but it is still the same. Now it's driving me crazy. So what could be the possibility of this kind of problem? I dont want to go back to the same mechanic again because apparently he cant do any better. Your help would be really appreciated. thanks!

| The air quality control system on my Sonata , which is a part of the 2006 Sonata LX Auto Air Conditioning, has become very inconsistent It operated as describe in the manual for the first 10 months now will not switch to inside air when exposed to exaust fumes. Has anyone had this problem? My dealer has no idea on how to fix it. Hyundai has not help! | |
