HVAC - Non Auto...P.O.S.

Anyone out there disappointed with the HVAC NON Auto function? Me, I'm disgusted. Why can't the temperature output ( non-auto) be linear. Up one degree= it gets SLIGHTLY warmer. Down one degree, it gets SLIGHTLY cooler.

Those that have been around the garage for a while know I've written about this before.

Today: Started the car and the last setting was 73. Jeep warms up and the HVAC output is too warm. Set it to 72 and one minute later cool vent air comes out.

Driving from Virginia down to NC. There's a lot of elevation changes within a short distance. Top of the hill with cool temperatures outside, the Jeep commands heat output. In a valley with warmer temps...now the Jeep commands cooler output. NEVER stays constant and the temp swings are too great.

Anyone experience this? I wonder if there's a possibility to turn off this pseudo auto. I'm up to-date on all TSB's and still this is a POS.

Re: HVAC - Non Auto...P.O.S.

Mine performs almost identical. 72 is somewhat comfortable. 71 and you get frostbite. Bump it to 73 and your skin melts off. I love the upgrades from my 11, but the HVAC performance in my 14, well, quite frankly sucks.

Try going back and looking at your receipts and verify they have done this flash.

http://www.wk2jeeps.com/tsb/tsb_wk2_2400515.pdf

I have an early release 2014 and my HVAC was similar, it was terrible cooked you in the winter time no matter what you did. The flash above completely fixed it now I just put it on 71 and leave it there year round never need to touch it. One thing I do remember is that this flash did not show up on the list when they checked the jeep for available flash updates. They had to manually find it and select it and push it to the jeep. Mine was not in the date range but they still loaded it and it did completely fix it. so id just double check to make sure you have that one because if all they are doing is loading from the available flash list you may not have it. If not id print the TSB and take it to them.

Also after I had this flash on mine the HVAC would not operate correctly at all until I pulled the battery cable and let it unhooked a few hours and let the jeep reset itself and come back up.

Hope you get it fixed I know the frustration in dealing with the whacked out HVAC. Good Luck

Mine, at 40,000 miles now (2104 Limited) has started doing this recently, thought I was imagining it, guess I will check into the TSB above. Thanks!! Dave
