Happened twice in 3 weeks, outside temp was ~ 10C (50F). I have 07 V6 with auto climate control. Immediately after start, the defrost control (on the driver side) automatically activated, ie, the LED lit. I believe this control automatically runs the AC too. I have a habit not to run AC while the engine is cold, also no frost/fog on the windshield so there is no need for the defrost function. I had to manual depress the button to shut it off. Just for curiosity, I shut off and restart the engine, same thing. If I remember, the LED is lit even on the accessory position (before the cranking the engine). Is this normal? I maybe wrong on this, in auto control, if defrost is required, AC will activate but the defrost LED is not lit??? |

| We love our 2004 Sonata LX and have many upgrades including AUTO heating and cooling. Bought in winter of 2003. Could not get heat, so back to the dealer - nothing wrong. Each September since take long trip. Gets cold, cannot get heat unless we put it way up past 75 degrees. Each year into dealer with complaint. Stupid people, nothing wrong!!!!! Do they drive our car? Driving through mountain pass in Sept. very cold. AUTO did not work. Tried every setting. Kept track of exact setting. Had to get it close to 88 degrees to get heat. Wrote letter to dealer, had it in. Got their temperature gauge and tested cabin temp. OK, nothing wrong. AUTO not working properly but dealer said basically have to put up with that. (stupid customer again). Defrost will not work on AUTO. Did they drive car in mountains? NO. Just got little thermometer out! Recently started pelting with rain when we were out. Real downpour. Inside windshield, side windows and rear windows inside started to "fog"up. Of course AUTO was useless. Tried all sorts of settings. Seemed neither "defrost" - front or rear-could clear windows. Finally in pouring rain had to open windows so that could clear off windshield and try to keep it clear. Very, very dangerous. Been bad if we had been on the freeway. Stopped at a store. Had to sit 20 minutes first with windows up and then windows down (in rain )to clear off windows to be able to drive home. Wrote dealer, AGAIN, with copy to President of Hyundai. Woman from agency called this morning to tell us nothing was wrong with car - they have not had it in since this "fogging up incident" but based on when we had it last month! Agency would be willing to buy car back from us at a very good price and arrange for another. Told her we loved the design of our 2004 Hyundai Sonata. That did not like th enew ones. That we wanted ours fixed once and for all. We are going to write to National Transportation Board and have no idea where to go from there. ?Attorney. ?What kind.?Attorney General. Now scared to get on the road in rain, especially freeway. We feel that the defrost system, the heating system, and air conditioning system has a defect somewhere in the computer, software? or ????? Anyone else had any problems like this. This woman told us a Hyundai representative did look aat our car when it was in the shop last month. Service Manager did not say that - just said he had talked to Hyundai people in California. We are so disappointed. We love our Hyundai, but it seems that it is only suitable to dirve when it is not raining hard, is not overly hot. In other words, a "fair weather car". We are fighters. We are not going to let this go. We paid $1,000 extra to cover the computers when we bought car. We want it fixed correctly. Any help anyone can give us would be so appreciated. | |
Since we got our car in September 2003, our AUTO has not worked properly.No heat, defrost , no a/c. We have it in the shop every year but they tell us nothing wrong. When they put a therometer in the cabin they say temp is OK. However, they are not in the car when it is cold, raining and defrost does not work properly. Anyone else have these problems.

Can someone help me? I have a 2006 Sonata. The "outside temperature" reading says 140 (it's only about 30 degrees outside right now). I can only get heat if I set the temp on "HI". Is there a quick fix such as replacing a fuse or something?

I just bought a new Sonata. The A/C does not work. The fuses are good. Compressor is not working. Could it be a bad compressor? or maybe they forgot to add Freon? Any thoughts would be appreciated

Replying to: molly44 (Apr 12, 2008 7:48 am)  But, what do you mean by "not working"? Cold air doesn't come out when the A/C is on and the temperature is set to the coldest setting, for example?
