I know this is a common problem, I've been reading all the posts I can find on the subject. I have practically no heat coming from my driver side vents. It is still blowing hard, its just cold air. The passenger side is better, but still not what it was new. This is a 2015 Jk. When I first bought it, you would almost get burned if you held your hand in front of the vent. Now I can hardly tell if its any warmer than room temp. I really hate dealerships, so I think I'm going to try flushing the heater core out myself and see how far that gets me. If I can't get anywhere, then I guess I'll have to bring it to the dealership. My questions are: Has anyone had luck unclogging their heater core by flushing it out? I have also heard about installing an in line filter in the heater core line to catch any further derbies floating around in there after you either get a new core, or fix your current one. Has anyone installed that and what are your experiences with it?

Hey doctorsteve. I noticed you said you had the heater core replaced and that it "Was fine after that" Is the heater core and heat inside the vehicle still working correctly? Are you having any issues with the heater on the driver side or either side for that matter?
I don't have it anymore. But once it was replaced (under warranty), the heat was fine. It initially was not blowing hot air at all on the driver's side, I can't remember about the passenger side. But there are numerous threads on this topic. There was some shit that got into the radiator and gummed things up in the heater core. The dealers know about this. Don't let them bullshit you.

My 2013 JK is having this same issue (no heat on driver side) and its cold as heck here in Missouri lately. I had the heater core flushed and the heat worked perfect (very warm) for about a month and now its back to exactly how it was, no heat on drivers side. I desperately want the heat back but am very upset about the cost at $1,850 for a heater core replacement. Maybe I would do it if I felt it would actually be fixed but my understanding is that the problem will come back. So, I'm trying to figure out what is the best approach to getting this problem resolved?
1) Does anyone know if having the heater core replaced does indeed fix the problem? (for a reasonable amount of time that is)
2) I'm seeing this article from January 3, 2018 http://www.carcomplaints.com/news/2018/jeep-wrangler-heating-ac-lawsuit.shtml with a headline saying JEEP WRANGLER HEATING AND AC LAWSUIT IS OVER. It goes on to say The plaintiffs say they finally talked Chrysler into paying all but $300 for the repairs. then a bit further down it says No details of the settlements were released. what the heck does that mean? Are they saying Chrysler is going to be upright on this issue and correct the problems they hid from people like you and me? Does anyone know?

I also flushed mine last year and I had barely any heat below 20F on the drivers side. Fed up with it this year, I did the shortcut swap found on Youtube and have to turn the heat down regularly. If you go this route, just be extra careful cutting the inlet and outlet pipes and sliding the core into the slot behind your controls. It's a tight spot but doable. Saves you $1600.
Thank you @Dugzilla! You Saved me a ton of money and time, this is exactly what was causing my uneven heat in my 2014 Wrangler. As soon as I cleared napkin that had fallen all heat problems fixed.
