Santa Fe (CM - 2007-12) :: 2009 A/C Malfunction Blowing Hot Air Randomly - Control Not Working Properly?
Mar 10, 2015
My wife drives a 2009 Hyundai Santa Fe Limited which we bought new back in 09. she has put roughly 140,000 miles in that time span. We have religiously followed all required maintenance routines; this is the first major issue we have EVER had with our Santa Fe. The issue we are having involves the AC unit. Instead of blowing ice cold air, the air vents are blowing hot air as if the heater is on. I have check all major AC components and everything is working properly. I believe we are having a controls issue.
At one point, all vents would only blow hot air. The other day, the passenger side vents started blowing ice cold air while the driver side still blew hot air. The driver's side has not blown cold air since this issue started about a week ago. We do have dual climate control; I have tried every possible combination of controls to see if it's a particular switch or button; however, I have not had much luck.

Been having an issue lately with the AC system on my 2010 4.6L F150. The AC system is not working properly and is only blowing air the same temp as outside. In other words, if its 60 degrees in the morning the AC will blow cool, but later in the day its blowing warm. Pushes air no problem, but living in Florida, it's mainly warm air. Compressor clutch is kicking on and off fairly rapidly when on max AC setting (5-10 seconds on, then 5-10 seconds off). Hooked up gauge to low pressure side and the readings were 60psi WITH compressor on, then fell to 30psi when the compressor turns off. Where to start? Haven't done too many AC fixes before. Potentially a bad compressor? Overcharged lines?

However, selecting Mode setting to the floor on the climate control build (as I read) does not seem to turn off the AC from running to off with outside air only. Also, the OFF button does stop everything but once the fan speed is turned up its cold air blowing.
I read through the entire section in the owners manual and there is nothing mentioning it will run if AC is not selected nor any other over ride procedure. I am thinking this is a unique SF Limited issue and solutions for other models don't hold true for me. With the temperature much hotter its not difficult to feel the difference blowing out the vents.

I have been having a mildew smell when using AC. I purchased a foaming cleaner that is mean to be sprayed by inserting a small tube in the evaporator pan drain, but the design on my santa fe drain hose prevents the tube from making it to the core. It always gets jammed up at firewall because of a 90 deg bend. Is there a port on the housing that allows access to the core?

I recently put in a new compressor and accumulator. I didn't change the orifice tube since it is almost impossible to get to. I added freon and oil with dye and it would work fine sporadically sometimes it wouldn't get cold at all other times it would be freezing. This lasted about a week. I noticed that when it was hot the clutch was engaging fully but I felt the pipe near the firewall and it wasn't cold as if the compressor wasn't compressing and then it would start compressing and it would get cold. The compressor sounds different when it was making the car cold. This led me to rule out a problem in the air control doors. Now there seems to be a leak which is bad since it runs out almost immediately. The problem is finding it since there isn't any oil residue or freon dye where I can see.
(Looking for some shortcuts where I don't have to remove the vacuum brake, brake booster to change the orifice tube?)

It seems as though whenever I turn on the AC in the car (and sometimes even if I don't engage the AC) all the windows lock and only I can control them from the driver's control panel...

A/C on my 2006 V6 3,3L Sonata just stopped working properly today when driving away from a supermarket, it blows only very hot air regardless of the temperature you choose on the display. It worked fine while driving to the supermarket and nothing remarkable happened to the car while I was shopping. All lights on A/C display, fan speed and everything else works fine, it just doesn't react to the temperature button at all.
I already checked the 10A A/C fuse under the bonnet, it's fine. There is an A/C relay in fuse box that I can check tomorrow but I suspect the fault to be somewhere else.

2010 UK Santa Fe manual box, suddenly will not set Cruise Control. At same time gear change advisory indicator also stopped working. OBDII tester will not initiate to check things out but first time I have tried this. Fuses checked all OK (I think).

I have to press Cancel before I can get my cruise control to work. I had a problem about a year ago where my cruise control wasn't working, and found out that a blown brake light fuse was the problem. Now I turn my CC on and the "Cruise" light comes on, I then press the set button, and nothing. I then press the cancel button and then the set button and then the "Set" light comes on.

I have an 03 Ford Ranger 4x4. Great truck and runs great just with one small problem. For whatever reason, every single time, the a/c only blows un-cool air (not hot) when I start the truck. Then, and only then, after about 30-40 mins of constant driving around does the a/c start working properly and blowing COLD air. After that it works great but it always takes about 30 mins after I start the truck for it to work correctly.

I have this weird problem with the cruise control of my 2002 elantra gt: I cannot set the cruise control at 30 or 40 mph, but I can do it somewhere above that (just went to the highway and set it around 60 mph). What could be the problem? Do cruise control systems need calibration or would I have to replace it?

I have 2011 Elantra that the cruise control is not working properly. It started out that I had to slap it to get it to work. I have to push the Resume button to turn on, Cancel button to set, set button to resume and the on/off button to cancel. Was told I need a new switch assembly. Done that and same problem. Shop checked brake light switch and said it was working properly, but I think they just meant for the brake light and it was not sticking. Even had steering wheel pulled and put dielectric grease on the wiring harness.

Me and my fiancee have a 2013 Camry SE and we've been having issues with our fuel gauge... It randomly will just stop working... First time it happened she just got in the car from work and it was at empty. When she got to work it was at half a tank... It took about 20-25 minutes of driving for it to slowly reach back to half a tank.... What could/would cause this malfunction?? And then today on her way to work it did the same thing..

I noticed today that the temp got to be about 70 degrees today. I went to put on the ventilated seat, but it did not blow cool air. when I first got the car, it felt like as soon as I pushed the button cold air came out, It actually felt weird at first.
Now I can hear the fan going if I turn everything down, but it did not get cool.

I have a 2005 6.0 f350 lariat... My climate control doesn't switch very well I can get it to go to floor sometimes after 15min of pressing the button. The vacuum pump is good the tank has no cracks. I feel that the system is either plugged up or has a leak. I cleaned the tank after my hub seals went and it sucked a ton of dust and dirt through my wheel bearings in to the tank. Is the vacuum switching part of the digital display? Or is there a separate part?

I just bought a very nice Lexus 2007 with a extend warranty from Toyota. This car is a dream to drive but one problem I have encountered, how to fix is the Climate control feature.
Sometimes my unit works properly then it stops responding. The problem I'm having is that the climate control button when pressed wont stay on the control setting on the Nav screen and goes back to the radio station screen.
I also can't control the temp up or down on either driver or passenger side. The only way it works is by using voice commands. I can't turn it off at all. I m going to take to the dealer but they said they never heard so a thing. But I showed the dealer today and he said there is a problem.

I just bought a 2007 Santa Fe 3.3ltr with auto trans and all wheel drive. When I purchased it the speedometer did not work. I bought the VSS gear and installed it and now my transmission does not shift properly. Also I had it to the dealership for an ECU update and they said that their computer could not connect to the ECU.

Back in March I started a thread regarding my 04 Santa Fe 3.5 which would not start after a spark plug change.
After a ton of research, & a smoke test on the intake I came to the conclusion that there was an issue with the throttle sensor as I unknowingly opened it when I was removing the intake to get to the last bolts behind the manifold. Shortly after my post, I decided to bite the bullet & buy a junkyard TB out of another Santa Fe 3.5.
After installing the new TB, the car now starts but runs extremely rich. I am now getting the code p2135 for Electronic Throttle Control System Malfunction.
Luckily up until this point I haven't needed the Santa Fe as it is mainly a winter vehicle. However, winter is quickly approaching & I would like to have her running before the snow starts to fly.

I have a corolla 2010 S and I think the blower is not working properly. It work in all speeds but in the max speed (4) you could hear and feel that the air flow varies. There is a little noise coming from the glove compartment. I already change the cabin air filter and still do it. I have to change the blower ?
