Hello, I have 2015 Kia Optima with 2.0 Hyundai Nu Engine. When car is Idle and A/C is on, engine vibrates a bit. Not so much vibration but my old Toyota doesn't have that problem. Is that normal? I also noticed that RPM does not increase when A/C is on at idle. RPM is at about 650RPM to...

I think this may have been discussed here before but if so, I couldn't find it. The issue is, when the sunroof is open, if you put the AC on recirc mode, after a few minutes, it automatically switches back to fresh air mode. This is described here in the Stinger forum...

Hi everyone! I'm planning to buy an Optima plug-in but I can't find any official tech info on the climate control; what is your experience with it? Is A/C pushing fine? Is A/C working in full electric mode without turning the gas engine on? Can't find info about heater too: does it turn the gas...

Hi everyone i have to wait 3 weeks for my nearest Kia service to look at my car. I was hoping if you guys have bumped into this but my A/C won't kick on sometimes. 98% my A/C will start automatically once i turn the A/C on. when i hit the button to turn the A/C on it will not even turn on...

Car a/c makes noise when on or off, when turned on the noise gets quieter and the air blows cold. Any ideas ?

Have to replace my a/c condenser , got a new one but the fitting from the new one does not match the fitting on the old receiver drier. After checking around on the internet none of the ones match from receiver/dryer t o the condenser. Anyone have this problem.

Hello! I just recently bought my Optima Hybrid EX, and noticed my first issue yesterday! Yay! :dry: So, when the A/C button is activated: light is on, vents should be blowing cold air. Right? Well no, they are blowing out heat. However, when the A/C button is deactivated, light is off, vents...

How hard is it to replace the a/c condenser on this car it is a 4 cylinder.?

Had it since new, 110,000 miles. Has been getting worse, now A/C will not cool at all unless at high speed. I sat in the driveway yesterday, if i rev it to 4 grand it starts to cool. Washed down the radiator, cabin filter is clean. I know this has been a problem on 2011's before. am i looking at...

anyone else have a 2011 or up optima? My SX blows barely cool air... So i'm assuming it needs a recharge BUT what could have caused this? the compressor runs, blows its just warmer air. O ring? condenser? has anyone had any a/c issues? what did it end up costing you? I'm trying to figure out how...

My first real problem especially in Houston. Everything else is working good. Love to hear from any that have experienced this before. Got the car in middle of 2013. Thanks.

I posted this on another national site, but forgot to here. I have a 2012 EX base, which has been on the road since December 23rd, 2011. It started to get weaker and weaker over a pretty long time (like months) until it could barely blow cool air, especially while rotting in traffic. So, I...

I'm still trying to get used to the A/C unit in my Optima and one aspect still has me scratching my head. Whenever I'm a few minutes from my destination, I like to switch the A/C off and switch the vent on in my vehicle to get all the A/C lines blowing ambient air to minimize the condensation...

So about a week ago I started to notice a horrible smell coming from my A/C. It would start but then fade very quickly but, recently, it is not fading away anymore. I know that's where it's coming from because I don't smell it unless I turn the A/C on or until the natural air flow starts. If I...

Hey all! About four weeks ago I purchased a CPO 2012 EX. I wish I could say I joined the forums because I'm in love with my Optima, but I'm not yet. Unfortunately, I joined because I've only had the car four weeks and am having some serious ongoing issues with the entire heat/air unit and I...

Over the past several weeks I've been having some issues with the A/C. At first it would blow fine under 35mph but after that its like it would shut the A/C air flow down dramatically(not in ECO mode either). Took it to the dealership and of course they couldn't "replicate the issue." So now...

Hi, I read up on how to remove the A/C compressor bracket, which involves relieving tension in its belt by adjusting a tension adjuster. Anyone ever do that, can you describe it generally? The information on Kia tech info says you just turn some bolt to relieve pressure in the belt and remove...
