Sonata NF (2006-10) :: 2009 - Climate Control / Front Defroster Always Comes On In Cold Temp
Nov 8, 2012
My 2009 Sonata Limited always has the front window defroster come on in cooler temps when the climate control is set to AUTO. This is aggravating since it shouldn't do that. I took it in for service last year at this time and they didn't find anything wrong and I gave up arguing with the dealer about it.
Is there a sensor or something that is out of adjustment? It comes one when the temp is about 40F or lower and you just start the car after it's been sitting cold. I don't notice it so much when I am out on multiple errands.
Another thing that I notice is that I can never just turn the fans on for air circulation when the temps are moderate, not needing A/C or heat. If it turn the fan on, it always seems to blow cold air feeling like the A/C is on, even if it is not in AUTO mode. I complained about the same thing and the dealer said the unit is operating OK.

On longer trips, over 20+ minutes that the interior temp does not hold the current set climate control temp? If using sync on both sides, the temp in the cabin seems to creep down and you have to keep upping the setting and then reduce it because its too hot.
We have an older 2001 Infiniti I30 and it keeps adjusting to hold the right temp.

I haven't been able to find the solution to change C temp readings to F on my 2009 ES350. The car is Canadian and I'm in the US and although it's not a big deal I'd like to change it over. The importation company already changed over the speedo and so the cluster reads F degrees and Miles. Just that one last change to make it all match up.
I read an old thread on the earlier generation that the body control module needs to be changed. But, nothing on this generation. Lots of people trying to go metric from English so maybe we could even trade parts to make it happen.

This might sound like a stupid question, but how should the climate control operate in cold weather when set to auto?
I have a 2011 screw, when its cold out, and I start the truck, cold air blows out of the front defroster when the climate control is set to auto.
The fan on my previous ford vehicles would not function till the engine reached operating temp. Then the fan would turn on and blow warm air to the lower vents.

I have a 2009 Hyundai Sonata that has the digital display for the climate control- which i am assuming is the auto climate control system that is talked about on here frequently. The problem is that the fuse for the climate control system continually blows, causing the display and all controls for the climate control system, to stop working. Put a new fuse it, blows again.

Recently noticed that the automatic climate control on my 2006 Sonata stopped working. The temperature readout still shows desired interior temperature but nothing happens when dial is turned all the way up or down. When in manual mode, the heater fan will adjust faster or slower when dial is turned so I still get heat/ac but only by dialing manually. If I switch to automatic mode, the fan will operate in whatever setting it was in when in manual mode. What part do I need to replace in all likelihood and how hard is it to replace?

The buttons to change the temperature in my 2010 Prius don't do a thing... The temperature is cool-ish as long as you have the AC turned on, and stays the exact same as you increase the temperature until you get to 85 and it maxes out, then it starts to get warm. As soon as you go to 84, it's cool again.

So today it was 101 and I figured I would put the AC on auto but when I set it to auto the temperature defaults to 72. Is this normal and can I change it? It seems like the climate control in auto mode go off of the outside temp, if hot outside blow cold inside and vice versa. What is the point to auto AC if I manually have to set the temp?

When I turn on the car the internal temp number flashes for about a minute. The AC blows cold and I haven't noticed any issues with the HVAC system. Why is it flashing?

I just purchased a 2014 Avalon XLE Touring. One thing that seems to be a slight problem is the A/C setting. To get the car to cool down I have to turn the setting down to about 66 to make it comfortable and I know it is not 66 degrees in the car. Is there some way to calibrate the temp reading?

From time to time, climate control will stop working. Buttons are not lit up or responsive, fans do not work, and computer doesn't show outside temperature. Problem can last a day, an hour, 10 minutes, or any other time frame. Most of the time once it stops working it will not start working until left parked and locked overnight. Sometimes when we start driving it would all of a sudden start working on its own. This has happened during multiple seasons and multiple weather conditions.
I took the car to Lexus dealer who decided it would be a smart idea to replace the whole climate control unit in the dash, well this past weekend the problem occurred again with brand new climate control unit in place.

i have a 01 b5 GLX 2.8L with the automatic climate control, well on occasion my temp will be reading fine than all the sudden drop to -36 degrees in 4 degree increments. when this happens my ac thinks its cold outside so it stops blowing cold air and blows hot air. i have to let the car sit with the ignition off for 15 min before it will reset. Is it my temp sensor that's bad and if so where is it located at?

RX450h Climate Control ... This is annoying and all my riders complain about the A/C Auto mode on this car. Here is the issue in Auto Mode with the inside temp set at 72 degrees, and the outside temp is cold anywhere from 55 to 65 degrees the A/C always blows cold air into the car. I can never get heat to flow into the car. The manual says that auto controls the a/c flow, fan speed, and vents like auto in almost every car. What is wrong here? The A/C is always on blowing cold air regardless of the temperature set inside the car. To me it seems that the temperature setting for both passenger and driver do not work.

I just discovered a flat on my 2006 Sonata (4 cylinder - 93k miles) - I changed it and put the temporary spare on - as soon as I got in and started it, the ABS light and the ESC off light came on. Is that normal? I plan to get the tire fixed tomorrow and to put it back on - just curious why those came on.

Recently my Climate Control System on Gen 3 has been misbehaving. A few weeks ago, I could not get cold air out of the AC, and then just as quickly as it stopped working, it started working again. Then yesterday, I started noticing coolant temps on the Scan Gauge rising to 215 - 220 F, which seemed quite a bit higher than the 195 limit I had set for operating with grill blocking, so I turned on the Heater and brought it down to 195, and when I got home, I checked and the coolant level seems OK, and it was under pressure.

Just stopped working. The fans of course blow fine and the air vent changes from top to bottom and the like. I checked the fuses and looks OK. I measured the voltages on the pressure switch and they read +5.0VDC and +4.7VDC to ground. The pressure switch itself measures 10.9K Ohms and 6.2 KOhms to ground from the two left pins. Is that the Ohms for LOW R134 ? I will try measuring with a manifold later but thought this might ring a bell. Is this style switch able to be JUMPED ? To see if it is only low pressure ? The ones I am used to have only 2 pins and this has three. I read +2.6VDC on the compressor clutch.

I have a 2009 Hyundai Sonata. The a/c air vent is not working on the passenger side. The vent on the drivers side is working. I believe it is the temp door actuator? Can we fix this on our own? Mileage is over 60,000 miles? That is the only problem I have had with my car.

Lately, in my 2004, with the climate control OFF, and recirculate setting OFF (outside air selection), I seem to still be getting cold air in thru the vents. The air flow selections are all working appropriately between defroster, feet, vent. When I select the OFF button, the fan stops but the last selected air flow stays highlighted - and the OFF button is still black (or, unselected).
QUESTION - I swear I remember the OFF button highlighting when turning the climate control OFF. Am I just imagining this or could it be the source of my air leak? Is your climate control OFF button highlighted when you turn your climate control off. I need a reality check.

I purchase a pre-certified Hyundai Sonata 2015 from Rockland Hyundai just 2 weeks ago but I didn't pay attention that the climate control has no display, the heater and the AC work fine but no display.

My 09' has developed the abrupt downshift issue at 20 mph when cold. Once the transmission is warmed up, the problem goes away. There is a Service Bulletin on this problem so it is known and a fix is in place. The fix according to the Service Instruction is to remap the transmission software.
How this remap affected their vehicle. My car has been returning great gas mileage, and I am concerned that this fix could hurt that. If mileage is adversely affected, I'd rather live with the downshift IF it won't hurt anything.

Basically when I have it cranked on high (level 4) it feels like its blowing on level 2. some times when I start the car it doesn't even turn on. I have to tap or hit under the glove box for it to start. Is it wiring or could it be AC Blower fan or something else.
