Kia Sorento Heating and Air Conditioning



  • Like all the others it seems I too am having the same issues... AC blows only when it wants to. All was fine till I had it at the dealer for routine maintenance now at idle it does not blow cold or hot. not till I start moving does it work. now it seems to not work at all. any suggestions as to how to replace the blower motor. Checked all the fuses and relays and all is good. Next is replace the blower... Help?

    I had an 03 sorie...and you had to access the entire circuit board..and yes it is a pain in the butt to get to and yes the diode light requires a little skill to attach.....wasnt worth my time and effort to fix.....with over 100k on the sorie...
  • I'm beginning to think the same way. Ours has over 100K as well and we are probably going to be looking to replace it in another year or so. If it's a lot of trouble and there's a chance I could break the control head in the process, I think we can live without a lamp behind the knob.

  • ATC Unit controlling everything to do with heating and A/C has died. Permanent heat coming from air vents.
    Had car in for a gear box refit and came back like this. Fuses seem ok, unit had both plugs fitted to rear.
    Help - unexpected hot weather in Scotland and no A/C !!
    Kia Sorento, 2.5D, 2004.
  • Hi!
    We just bought a used 2003 Sorento and the A/C went out. We replaced the A/C compressor and charged the system with the correct amount of freon and worked for 5-10 minutes and shut off. We are now thinking that the original A/C compressor wasn't bad at all. It's like something is shorting out or????? Please help if you can! We are in Texas in 108 degree weather!! Thanks so much!
  • Without sounding redundit, my wifes 2007 Kia Sorento LX 4X4 automatic has these problems:
    1. On occation the AC will just quit putting out cold air, though the fan continues to blow (hot air)
    2. On occation the Heater will just quit producuing hot air and cold air is being dispursed.

    In addition, we have noticed that when breaking at night, the light will slightly go dim. Not sure if this is related, just FYI. My wife is very tenatious as to her up keep and regular maintenance of hr vehicle. With over 30 + days of triple digits, and winter nearing, I want to get this corrected ASAP. Any directions? I have read that AutoZone will do a diagnostic test and provide part replacement number.

    I will keep everyone posted as this situation develops. Noticed NO HEAT ....Checked the coolant tank and it was empty...radiator was full...Dealer pressure tested system and no loss of fluid was noted...In drive home I noticed I still have NO Heat in the rough range selection of 70-79 deg. I am monitoring coolant tank to see if level drops....Has anyone solved this problem? Thanks, Rick
  • I know this is way late post but we had similar issue after work was done. Found that there was air bubble in coolant system due to hose being removed during work. This caused car to not have heat. To bleed out just popped the radiator cap and ran air out and works fine now.
  • my sorento will not switch from hot to cold any more. ive been told it "might" be some sort of actuator door or blend door something like that. i can appreciate my mechanics advice but he has done some repairs for me in the past and they took lots of expensive trial and error. before it finally stuck on cold the problem was intermittent and i blew it off as the thermostat(im from old old school) but the the engine temp was fine according to the gauge and i went ahead and had the guy flush my radiator with pressure because he said it was much better than just changing out the fluid with new.
  • i have the same model and year. i have never seen these bulbs or indicator of hvac. are they down at the console next to the cubby? ive had kias since they came over from korea almost and the only serious complaint i have had is the electrical system. the bulbs on mine are always burning out. i mean ALWAYS. i have the cyclopse light over the back end out now. i also own a 1997 mustang and have never ever replaced a single bulb. it has 115,000 miles on it too. let me know about those lights please
  • WOW, i have the exact same problem i just had a difficult time explaining it. glad you posted this brother. i hope to read down and find a less expensive way to repair it. like you i plan on retiring it soon but i tend to get attached to cars. the sorento has performed quite well. quick acceleration for a v6 and all the airbags make me feel at ease for my familys safety when theyre out. its been very dependable for the last 8 years too. i have 85 thousand miles and besides the constant replacing of the light bulbs we have enjoyed it on many a vacation and around town.
