#89 of 98 A/C not working by aquavishal May 02, 2009 (4:43 pm)
Hi All, I have 2003 Santa Fe LX with 77K miles on it, It has Automatic heatiing and cooling controls installed. From the last few days when I started A/C first time in this season, it was not blowing the cold air. I verified it for 5-7 days by turning-on /off A/C but it surely not working. I went to Hyundai dealer and had it checked for 100$. He told me that there is some problem with clutch tied with A/C compressor and need to replace clutch and rebuild A/C compressor. I learned that this seems normal wear and tear. Total cost with labor is close to 700$   Seeing the cost too high, I thought of verifying with my local mechanic. He checked and told me that A/C is not getting power from electronic controls. and need to see where electric current is breaking?? this response was totally different than what was told by dealer - no relation with A/C compressor or clutch.   now this become complex, I thought of verifying it with Firestone. They also had it checked for 40$ and told the same electric current missing problem. They double checked that A.C and clutch seems fine. They also told me to investigate fully with additional 90$ cost. Now I am totally confused. I would have trust authorized Hyundai dealer more than anyone else but this incident is puzzling me.   I would like to ask other people opinions and have they ever faced such an issue. Maybe any clue about or related to this problem. one thing to note here is tht FREON and other things are full and AC unit seems fine.   Please help Thanks and Regards Vishal Replies to this message: denvertrakker (May 06, 2009 7:32 pm) somedai1 (May 07, 2009 7:53 am)

Replying to: aquavishal (May 02, 2009 4:43 pm) My vote goes with your mechanic. The dealer is taking the path of least resistance - throwing parts at the symptom without understanding the problem. If there's a problem in the controls, then power is not reaching the electric clutch, so it doesn't pull in and activate the compressor. It does have a relation to a/c and clutch, just not the way your dealer told you.   I would certainly have your mechanic determine what's happening with the controls - that's more likely than a failure of the clutch/compressor assembly (although that's certainly possible).

Replying to: aquavishal (May 02, 2009 4:43 pm) anybody check to make sure the a/c compressor relay is not the problem?

I have a 2005 Santa Fe. The last week or so i have noticed that when i turn my ac on it will blow cold air, but then after i drive for about 15min. the temp of the air will start to get hotter. I have checked the freon level and it says it is at the perfect level. Has anyone run across this problem or have any incite as to what may be causing this.

Replying to: jmartin80 (Jun 04, 2009 9:39 am) check to see how the compressor is operating...
#94 of 98 Re: air or heater always on [dukesdad2] by mpuzach Jun 20, 2009 (12:27 pm)
Replying to: dukesdad2 (Dec 08, 2008 9:02 pm) To bring in outside air without heating or cooling it, just:   Turn the temperature controls to "Lo". Make sure that the A/C button is not engaged (green light is not glowing). Make sure that the recirculate / outside air selector button is in the "outside air" position. Set your desired fan speed.   As long as the outside air temperature doesn't exceed 59 degrees, no heating or cooling will take place. Keep in mind, though, that if the car has been sitting with a warm engine compartment, you'll need to drive it for a few minutes before the incoming air is no longer being warned by the engine compartment.
#95 of 98 A/C always on by srz948 Jul 14, 2009 (3:20 am)
Trying to get fresh air in my Santa Fe LTD was a little annoying at first but I think I have found a way to get fresh air into the cabin without A/C.   Turn off the AUTO button. Set the MODE to the dash vents. Set the FRESH AIR setting. You now have fresh air coming through the dash vents at the low fan speed. However as soon as you raise the fan speed the A/C compressor will come on even though the A/C light is not lit.(Strange). At this point I press the A/C button and the light comes on. Then I press it again and the light goes off. This sequence seems to shut off the A/C compressor and allow you to adjust fan speed without A/C.
#96 of 98 2005 Santa Fe - cabin fan is on all the time by fighterfoo Jul 27, 2009 (8:36 am)
I searched through the forums and didn't find a similar problem so I'm posting here.   My 2005 Santa Fe has automatic climate control, and even when the climate control is off, the fan blows at what seems to be hi-speed all the time.   The climate control acts normally (blows cold when needs to, looks like it's changing fan speeds when really warm, etc.) but the fan just blows at a constant speed whenever the car is on. Help!
#97 of 98 2003 Santa Fe AC air flow restricted by tg_santafe Aug 01, 2009 (11:12 am)
My 2003 Santa Fe seems to have an odd AC problem. The air temperature remains cold when running the AC, but periodically the air flow becomes restricted. You can hear the blower still working, the bit of air that comes out of the vents is still cold but you can feel very little air flow. Changing the vent knob to different positons (feet, defrost, etc) does not help. Turning the system off for some time, then back on will fix the problem. Seems to happen more often when it's hot outside. Dealer worked on it, changed the blower door and blower relay. Problem does not happen as often but still occurs a few times an hour when driving.. any suggestions?

Replying to: stonejd1 (Sep 03, 2007 4:59 am) I realize the previous post was from 2 years ago, but I'm having the same problem now. I want to clean out the drain myself, but can't find it. I've removed the glove box and found the space where the cabin air filter belongs, but can't find how to access the drain. Any help would be appreciated!
