Where and how to access the condensation drain hose on a 2018 Sportage.

Thanks.

No one knows? Someone in works thinks you need to access this from within the vehicle.

Anyone?

idle the engine with the air running, once it starts draining onto the ground, look where the drips are landing, then inspect the area immediately above that. unless of course, your drain is blocked, in which case you are just going to have to get the vehicle up on stands and take a good look around to find it.

if it's like on my Soul, then you can usually see a tube hanging just below the body frame on the left side, but as mentioned the easiest is just to see where it drips.
I periodically check for a wet spot under the vehicle when I'm using the a/c to make sure it's not plugged.

Here it is on my 2016 Soul

Both of my Kias have the AC drain hose somewhere in front of the firewall, on the passenger's side. My Cadenza (for whatever reason) had the rubber hose plugged and kinked, which was absolutely no surprise due to how I live in Fargo, ND and our winters literally are capable to doing ANYTHING to a car, whether you think the area is protected from snow or not. I wiggled the hose, and it went back into the downward pointing home position and literally POURED out condensation water, the ground looked like a water balloon just exploded. All was well after that.

Thanks everyone. Guess I'll have to try and crawl under there to find it. I've had a couple people tell me to access it from inside, but I don't have anymore details then that.

Well, since the evaporator (cold thing) is inside the cabin and the water (condensate from blowing warm, moist air over the cold thing) needs to go outside the cabin, I guess it is technically feasible that you could possibly touch the drain line from inside the cabin, but what you need to do is find it outside the cabin and make sure its dripping when the AC is running. If you have water in the passenger-side floor when it hasn't been raining but you have been running the AC, it may well be plugged up or kinked during assembly like TD's. In hot weather, you typically will find a patch of wet pavement under the car where it was parked after driving it. This probably is enough evidence that it is dripping. My driveway slopes up, and anytime I drive up it after using AC, and then get out and walk back down to the mailbox, I'll see a line of water where it dripped faster going uphill, which is all I need to see to know that the water is draining out. You have to figure out your own clues based on your situation.

Yes, still alive, but have not had the chance to craw under, as of yet. It's draining, so that was my concern.

I still don't understand why I'm being told that clogs are cleared from the inside with this.

Well, it really depends where is clogged, 1st of all, do you have an inside leak or it's dripping outside like it should? On couple of vehicles the hose can be seen from the inside of the vehicle, in many cases you unplug it from the condensator and blow compressed air to unclog it, but honestly in this vehicle I haven't had any problems with it so I haven't bothered to check.

Unfortunately, I learned where the drain hose was and how to unclog it too late. Week before last, I was driving our '17 EX and heard a strange noise coming from the passenger dash area during a left hand turn. This is my wife's vehicle and I rarely drive it. My daughter was with me at the time and said she heard it too but that it was only happening on left turns. I had to investigate this noise and had my daughter do a left hand circle in a caldesac in our neighborhood while I had the glovebox open. Sure enough a steady swishing sound. I had her stop and then I heard a splashing sound. Also, I noticed there was a small amount of water on the Weathertech floor mat. I now realized that we had an A/C drain issue. Went to YouTube and saw the procedure of a quick blast of compressed air in the drain tube to clear the clog. The tube is very easy to spot once under the vehicle. Located just right of center and rear of the main cross beam. I would say about a pint of water came rushing out! I thought my project was done but had yet to realize how much condensation had been leaking in the cabin. When I removed the floormats I was shocked to see that they were soaked! Thanks to my car stereo installation experience from 30 years ago I was able to lift up the carpeting and get her all dried up that day. I have now asked my wife to check underneath the vehicle everyday for drainage. As far as the root cause, I did notice that some leaves had made it past the cabin air filter. They must have dropped through during a previous cabin filter replacement. I will be checking for foreign material very carefully next time I change that filter!

No, I haven't found it. Had my wife take the car to the dealer to resolve. Drain was clogged, causing carpet to get soaked. She didn't think to ask him where it was located, however, they did say they fixed it from the inside, which didn't make sense to me.

Ok, the issue in having with mine is that the a/c takes a while to cool. I turn on the fan with the a/c button on and everything and it takes about 30 to 40 secs to feel cool air on the vents and I'm not talking about doing this on summer under the sun, I mean in my garage or anywhere else. Gonna have to take it to the dealer soon.

Perhaps you didn't realize that there is still ambient air in the duct work, so just like an in your home central air system, the warmer ambient air has to be forced out before you begin to feel the cooler air. Additionally, and a smaller contributor, the compressor and air exchange system doesn't instantly turn the incoming air cold.

Well, thing is, that it didn't worked like that from the beginning. Ever since I bought the car it has been working what you would consider normally, problem started few months after the expansion valve recall procedure was done.

Any significant change in outside temp from when it worked right to when it didn't?

Nope, exactly the same since we live in Puerto Rico and here it's summer the 4 seasons.
Variations aren't really significant the most could be around 15 degrees and that's in our "winter" season.
