Did you recently rush to buy a new vehicle before tariff-related price hikes? A reporter is looking to speak with shoppers who felt pressure to act quickly due to expected cost increases; please reach out to PR@Edmunds.com for more details by 4/24.
You should goto "www.hmaservice.com" and find the layout of the ductwork. This should show you where the valve-doors are positioned. The heat/cold one should be by the heater core. There are others that make the air come out of the defrost vents, floor vents, dash vents and recirculate the air.
Does you ventilation system change where the air comes out still. You could just have a hose that popped off.
What does your temperature gauge indicate? Hot, cold, normal? It's possible your engine thermostat has failed open and your engine isn't warming up properly as a result.
Consider that it just isn't COLD in much of the country yet...maybe chilly in the mornings. If the interior temp isn't set for 80 degrees (as an example) when the inside temperature sensor reads only 68 it isn't going to call down to the engine room for a lot of extra heater output. In other words if the difference between what temp you want in the car (via the digital temp on you climate panel) and the existing ambient interior temp isn't too great the heater isn't going to work hard to only heat the interior a few degrees
I have a fully loaded 1999 2.5 ltr auto Sonata. The previous owner botched a repair by cutting off the connector block from the wiring harness and connecting the cables to a non standard actuator with cable end twisting and insulating tape. As a result, the climate control doesn't work. I have bought a brand new actuator but have no idea which cable goes to which; the colour coding does not corespond. I have searched high and low for this area of wiring diagram to no avail. Can anyone help me PLEASE...
If I leave the temperature control in the cool range when turn off the engine at end of the day, I cannot get heat the next morning when turn the temperature control to heat range doesn't make a difference if I turn control to heat range before or after starting the engine. . If I leave control on heat range at night, do not have the problem. Hyundai dealer could not diagnose. Has anyone had this problem?
Hi There are 5 wires. The car's wiring has: Dark Grey x 1 Yellow x 2 Light Blue x 1 Dark Blue x 1
The wires of the actuator are: Red x 1 Grey x 1 yellow x 1 Yellow (With dashed dark stripe) x 1 - Not quite sure what the dashed colour is! Dark Blue (With dashed light stripe) x 1 - Not quite sure what the dashed colour is!
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.
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.
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.
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.
2008 Hyundai Santa Fe, the outside temp is stuck at 68 degrees. Have replaced the external sensor measuring ambient temperature and also the A/C controller. Still stuck at 68 degrees. Suggestions?

How do you know it is not running did you look at the clutch?
Thanks in Advance for ANY help related to my only issue with this car in 8 years!
