2019 Kia Ceed Air Conditioning Issues and Possible Interior Temperature Sensor Malfunction

Insufficient Cooling/Heating

A/C System Not Engaging

Air conditioning blows warm air

Hey! I've been experiencing some issues with my 2019 Kia Ceed (gas model), and I'm a bit cagey about visiting a mechanic since my last experience wasn't the best. Here's what's happening: my air con's blowing warm air instead of icy cold, the car's not heating or cooling properly, and on top of it all, the A/C system doesn't seem to be engaging. I suspect there might be an issue with the interior temperature sensor, but that's just a guess. The car's got around 140,379 km on the odometer. Has anyone else faced a similar problem and what was your experience with the mechanic like? Short tips or suggestions for dealing with this would be gratefully received. Cheers!

Hey there, I get what you're saying, had a similar problem with my 2016 Kia Optima. My air con wasn't blowing cold air either, and it was giving me all sorts of headaches. Turned out, it was a defective sensor cable connection causing the temperature misreadings. Dealing with it wasn't as serious as I thought. My mechanic fixed the issue by replacing the sensor connection and recalibrating it to ensure it read the temperature properly. After the replacement, the A/C system started working like a charm again. I'd suggest checking this out in your car as well, might solve the problem. Good luck!

Hey, thanks for your response! I see that a defective sensor cable could be my issue as well since our symptoms match spot-on! Glad to hear your Optima started working fine after the replacement. Just trying to get an idea here, do you remember how much it cost you for the fix? And has anything else popped up related to this since the fix? Appreciate your help!

Hey! No problem at all, glad I could help! As for the cost, it set me back by around 110€ to fix that pesky sensor cable connection. Not the cheapest, I know, but it did the trick. Since that fix, I've been all clear - no more messed up signals from the interior temperature sensor or any other related issues. I tell ya, it's been a smooth sail with the temperature control in my ride ever since. So, I'd say it was worth every penny. Try not to fret too much about it, just get it checked out and you'll be back to icy cold air con in no time! Cheers!

Brilliant! Thank you so much for sharing your experience. The €110.0 price tag does pinch a bit, but if it resolves the issue, I reckon it'll definitely be worth it. Better to have a working system without any problems, right? You've been super helpful, and I really appreciate it. I think I have enough information to deal with it when I go to my mechanic this time. Fingers crossed the air con will be blowing freezer-grade air soon. Cheers stay cool!
