I had no heat on drivers side vent for about 3 years. I finally found a video about back flushing the heater core and i did this yesterday. My heater now works the best it ever has since owning the jeep. It gets extremely hot now. I would try this before anything else as its about a 20 min job max.
6 hours back flushing with 90deg C CLR didn't do it, and neither did the 3 prior back flushes before that.

Your next step will be in determining the reason why your coolant was low. There's 2 common causes for this. 1. Radiator leak 2. Lower Intake Manifold gasket leak. The most common problem is a leaking radiator. The best way to confirm and find the leak is to use a radiator pressure tester. This is also in my diagnostics thread.

On another note, on Sunday, I noticed my oil filter housing was leaking and had Jeep replace it (it was warrantied, so I went to the stealership), so if it was the intake gasket, that would now be solved. However, I will pressure test it just to make sure...

Great write up and video. My 2011 JKU Shara just started making this same horrible sound this morning. Gonna check it out and hope to make use of the existing part as well. Otherwise, it'll probably take a week or more to get the part to Hawaii. Thank you!!!

No easy fix
There are no easy fixes with these heating issues, engine flushed heater core flushed. Rad flushed. Actuator door works as it is supposed to and all fluids changed. Should be a recall issue, apparently there is some kind of sand that is in block that clogs everything. Last Jeep I will ever own

3rd heater core in less than 3 years
Just got my Jeep back after having the heater core replaced, for the third time! 2011 JKU 130,xxx miles.
had my first failure January 2017 @ 110,xxx miles. I noticed The gurgling sound behind dash and then Coolant started leaking passenger side. Brought to the dealer to fix $$$. November 2017 heard the gurgling sound again and before it started to leak I brought it back again. Dealer diagnosis is in fact the heater core again. Dealer fixes under warranty. January 2019 heater core fails again!!! This time no warning (no gurgling sound) heat goes out and passenger carpet is soaked. Called Jeep to make sure it is still covered under warranty - it is. Dealer fixes it.
Any success stories directly working with Jeep? I called back asking what would happen next time since it is now past the 2 year warranty from the original service date January 2017. and if/when the heater core goes out again - do I have to pay out of pocket again for the same part same problem same ridiculous issue. I’m waiting for a supervisor to call me back.

No heat on drivers side vents and aux fan runs a lot
I am dealing with the same issue. I have some heat, but it’s not consistent and seems to be warmer on the passenger side then on the driver side. However, I find it strange that for some reason my auxiliary fan is running all the time, the engin temperature is normal, but th fan seems to come on after 10 minutes of driving and stay on, until I turn the jeep off. It is not hot, the operating temp is normal.
