JK Wrangler no or low heat fix. Blowing cold air left vent, heater core

JK Wrangler no or low heat fix

My 2012 Wrangler has had poor heat since I bought it a few months ago, the right vents would blow hotter and the left vent was cold, I searched online forums and found a few issues that other people had, like the mixer door motor or lever but mine was working fine. There is no heater valve on these JK's and JKU's! I took thermal images with my SEEK compact XR unit.
After all my research I came to the conclusion that my heater must be plugged. So I drained the anti-freeze system, unhooked the hoses to my heater core and flushed them both ways, hooked everything together and filled the system, warmed up while topping off the radiator, at this point I had NO heat at all, pure cold air, the pipes running to the heater core were also cold so I knew they needed to be bled out. I shut the Jeep off, pulled the top hose off and filled the hose until it ran out then reconnected fast, started the Jeep and BAM!, I had HEAT!! better than ever, all vents blowing scolding hot air!!

I hope this help others with the same issue, saved me from doing a heater core for no reason... phew!!

Also caught a video of the clean up of a rolled over 18 wheeler dump truck on rt 7 in New Milford... quite a bit of equipment to clean that up!

Work done so far:
I repaired the sway bar disconnect.

Found out the clock spring is under (extended warranty through Jeep, so it is replaced free if defective. So is the left cylinder head...

Mountain goat series 3” spring lift and some Joyroad MT200 35” tires. They work GREAT! This is the 2nd Jeep I installed them on (CJ7).

Skyjacker shocks installed
