Question about 2009 Hyundai Sonata

Open Question

2009 hyundai sonata climate control too hot or too cold

50,000+ miles, and in the last few months the climate control doesn't manage the air temperature accurately. It often heats the cabin way too warm, even when the temp is set to as low as 73, or often blows cold air (the display clearly shows it's running the A/C) even if the outside temp is 45 and the inside temp is set to as high as 82. It's as if the cabin thermostat is not sensing the cabin temperature correctly.

I also own a 2004 XG 350 and I agree with you. The first thought that comes to mind is a malfunction in the Auto AC control module (that's the virtical console unit which you adjust the fan speed, Auto, Mode, Recirculate, etc. are located). The other thought which occurs to me is that you might have a 'low engine coolant' condition (but that would eventually turn on your "Check Engine Light" and a code would be set indicating the Thermostat was not working properly). Did the Svc Mgr scan your vehicle for any DTC's (Diagnostic Trouble Codes)? If he didn't (or if he didn't have a technician do it), then you'll want to have that done so you'll at least know this may not be the problem. Sometimes the thermostat can stick 'OPEN" and the engine doesn't reach it's operating temperature (which is where you get the heat to warm up the inside of the car)... so, if the engine is 'COLD' so would also be the coolant and it's the coolant that brings the heat into the passenger compartment (via the heater core).

No heat 06 sonata only blows cool air


it most definitely is your blend door. It's a bit of a hassle but in the end it doesn't cost anything but a sore back/neck and hands. Take your time. remove glove compartment, and you'll see the blend actuator. I unplugged mine as it was stuck in 'cold' mode. after re-plugging it worked again and has been fine since.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

The air conditioner is blowing hot air, I have already added freone, could it be the thermometer?


A/C problems are one of the most diabolical to diagnose.... it either cools, or it doesn't... and all the reasons it doesn't accounts for every component in the system (compressor, condensor, expansion valve, pressure sensor (three-way switch), contamination, air box 'mode' doors not operating properly, door actuators stuck closed/open, A/C control module (head) malfunction, etc.
Best advice, have it properly diagnosed by a certified Hyundai Technician.

My Santa Fe loses exceleration, if you push on gas, it will not go any faster, usually about 20 miles. When diagnosed got code p2135. I was told there was a recall by hyundai for this. Is this right


Hello, There is not a recall for this issue,but there is a TSB (technical safety bulletin) by Hyundai for this issue that you are having with your vehicle for the code that was set. What this consists of is replacement of the throttle position sensor and performing an ECU software upgrade for the vehicles computer. The process usually takes about 45 minutes to an hour to perform at a Hyundai service department. If you are the original owner of the vehicle or it has less than 60,000 miles, this repair procedure is no cost to the owner. Hope this info helps. Gabe
