[QUOTE="MacGuyver, post: 430985, member: 18877"] So you didn't flush the heater core? Cold air on drivers side is a big indication that the heater core needs a flush. The sludge the guy shows is more than enough to keep it from getting super hot. The same thing was happening on mine, flushed it and captured what came out. Didn't look like anything did, but heat works great now. The problem the guy ran into was that he didn't get the air out of the system. Bleeding the system is really the hardest part of this operation. The other thing you might try is with the Jeep off, turning the HVAC knobs all the way to the left, pull J15 for 10 seconds, replace the fuse, then start the engine. I used to have to do this on my 14 to get the actuator doors into the default position on occasion. [/QUOTE]
