Where do you live? If it is really cold the compressor may not run.
How do you know it is not running did you look at the clutch?
#65 of 73 2003 Sonata Climate controls
Feb 12, 2011 (10:29 am)
I just changed the battery, and the climate control reset to celcius. How can I change it back to F°?
Thanks in Advance for ANY help related to my only issue with this car in 8 years!

I don't remember how to change from Centigrade to Fehrinheight (sp) but it is explained in your owners' manual. (My Sonata is an '05 & I'm assuming it basically the same as yours.)

I own a 2009 Sonata and at 57,500 miles the AC began acting up. It was set to 71 degrees, outside air was 80 deg. The AC stopped blowing cold then began blowing hot on right side of dual control. Hyundai replaced the temp controller. Two weeks later when I had the AC on it stopped blowing cold and started blowing hot on both sides no matter how low I set the temp or whether it was in manual or auto. Took it to dealer, they had my car for four days and said they could not duplicate. Gave it back and it is now working for the time being. I suspect this will be an ongoing intermittent problem. Yesterday I talked to a man who has a 2006 with a similar malfunction history and a history of unable to duplicate by dealer. His problem started around 56,000 miles and is still going past warranty.
#68 of 73 2006 Sonata A/C dead, not auto climate control
Jun 25, 2011 (10:04 am)
My 2006 Sonata A/C is not working. The compressor is not turning, nor is the radiator / condenser fan turning with the A/C showing "on". The fuse in the dash board, driver side is good, the fuse in the engine compartment (#7 think) is good and the A/C relay is good. (I know this by having replaced it with a new one even though the old one showed no signs of heat or discoloration). The A/C freon shows 70 psi both high and low side, enough that it should clear the low pressure cut-out. The lights on the controls (manual controls, not climate control) do light up correctly with requisite button pushes and such. OK, the fuses are good, the relay is good, the freon pressure is good, the light on the dash light up. The compressor does not turn, the condenser /rad fan does not come on with the A/C but works correctly with engine temp. What have I missed? The electrical plug is secure in the top of the rotary A/C compressor. Help, please.
#69 of 73 blower issues
Jul 05, 2011 (2:31 pm)
The blower for the interior fan on my 2006 v6 3.3 liter Sonata takes a minute or two to come on when I start the car. The heater is hot and the AC is ice cold, but it takes a minute or two for it to actually kick on after I start the car. Even when I turn the car off and immediately restart it, I have to wait a minute or two for the fan to come on. Even without AC or heater, the fan won't come on immediately. This is getting very irritating. Any similar experiences and suggestions for corrective action?

I have a 2008 Hyundai Sonata and have the same problem. It has been to the service center several times with no luck -- their answer "we can't duplicate the problem". They even asked me to keep records and took it back with the records, and still "we can't duplicate the problem". Then on 8/26/2011 the a/c stopped all together and wouldn't you know it was a day that the temp was 110 degrees. The a/c would not work from 8/26 - 8/29 . . . NOTHING! Was scheduled for service on the morning of 8/30. Get in the car to head to the service center, start it up and the a/c blows full blast as cold as could be! So no service center since I didn't want to hear the same thing . . . "we couldn't duplicate the problem". Anyone that has any suggestions or similar problem with a solution, please help!

Thanks for your message. I finally got mine fixed. The dealership could not diagnose the problem for me either (after spending $115 for a diagnostic). They ended up replacing the whole fuse box for $465 (parts and labor) and everything seem to work fine now.
#72 of 73 A/C working but not blowing in cabin
Oct 05, 2013 (2:39 pm)
I have a 2008 Hyundai Sonata, never had any problems with it at all, until this past year. My A/C is working fine - can hear the compressor kick on, the vent air comes out cold when A/C switch is on, but, it has stopped blowing air, no matter what setting level it is on. I believe there is just a short somewhere, because, usually when i run over a bump or encounter a rough spot on the road, the air magically starts blowing out air, and I would have no problem again for weeks at a time. However, in the last few days, the air has stopped blowing out all together, except for the vent air I spoke of. I've checked the fuses, and they are all fine. It's October, yes, but still 95 degrees here in Texas, and I need air! Any suggestions?

My 2004 Elantra had this problem awhile back. I thought it might be the blower fan. Turned out the rotary fan switch on the dash failed, had to be replaced. Works fine now.
