got the jeep back yesterday, new AC Head Control was installed. short story: it seems better, but i want to give it a week of commutes just to make sure.
more detailed version:
remote started car, ~40 degrees outside. AC was previously set to 65. (it was warm yesterday.)
got in car, cranked AC to 73, put fan on 3 or 4.
warmed up nicely, just like before.
after cabin was nice and toasty (15min or so?), i turned the AC down to 72 and fan down to 1.
after ~25 miles, the AC started pumping not-as-warm air (as expected to maintain a temp as opposed to getting to that temp).
the not-as-warm air did not seem nearly as cool/cold as what the AC pumped prior to the fix.
so yep. once the AC goes into regulate-the-temp mode, it does seem to switch to a different, cooler mix of air than what it pumps trying to hit your set temp. and that mix does seem warmer than before
. part of the problem was also that once it was in regulate mode, cranking the temp & fan back up (sometimes to ridiculous settings) would not result in warm/hot air again, and the AC would continue to pump out cool/cold air (making the cabin colder and colder). i have not had a chance to test that at all yet. i'll do my best to test over the next week or so and report back, but as of right now, i'm pretty hopeful that the problem has been fixed by replacing the AC Head Control.
(sorry if that was too verbose; wanted to be as detailed as possible.)
also, props to Mark S., service advisor at my local dealership; and Micheal, my star case rep (through 1800-iam-jeep). both were knowledgeable and professional throughout.
