RRT 14-050 Messed up my A/C

I just had the RRT 14-050 applied when I came in for first oil change. It totally messed up my A/C. Now when in Auto mode, it blows warm air through the feet vents even though it's 85 outside...

Anybody had that flash performed followed by issues with the Climate system?

Yep - Hard reset by disconnecting and all will be right with cabin comfort again. I had the EXACT same issue...AND had to fight my service advisor on it as he was "that's the way it is supposed to be"....AND he is one of the good guys (he must have been stumped at first).

Thanks, guys. I noticed this on the way home after having RRT 14-050 (et al) applied, but I thought I was possibly imagining it because max AC was still capable of blowing cool air.

Maybe I just need to get in the habit of pulling the battery cable every time the vehicle goes in for a flash.

Yep yep yep - same exact thing, A/C worked on MAX setting. So my service advisor said to leave it on MAX ... lol no kidding.

The sad thing was the dealer had no idea how to correct it. They checked and rechecked everything "all operating fine"
First thing i did when i got home was pull the cable all solved. Yes i have been doing that when they flash modules. Not the radio updates but the just the module flashes.

Part of the problem is this rapid rush (for market and marketing) to add all of these "goodies" in the form of electronic and software-based controls to vehicles. It's overwhelming the dealer service departments. Seriously. Technicians are not at all trained or used to dealing with complex (relative) systems like this. They certainly aren't experts in software-based systems. Plus, in this rush, information and training is lagging the actual product. I've met quite a few service managers that are just as frustrated as you might be.

You might laugh but...historically a service department never had to think about "rebooting" a vehicle. Traditionally, the self-contained modules that did exist shouldn't ever need such a thing. Service personnel dealt with mechanical diagnosis or electrical faults that were traced in wiring, not software going berzerk and acting funky. When confronted with this, the first response is "uh..."

Some service departments I deal with are starting to make sure they hire techs that have at least fiddled with computers before to help this a bit. But, most people who are good with computer systems don't want to be auto techs, especially with the pay rates and the manual labor. The solution is to hire systems technicians...but, they typically demand more in terms of pay (think of your IT guy), and commensurately your service costs will rise.

AC is working again, and with the new transmission flash applied I didn't notice any oddities even though putatively the transmission has been kicked into "re-learn" mode by the battery disconnect procedure.

It would make me happier if I were able to reconnect the negative battery cable without throwing sparks.

At least I have a torque wrench to get the terminals tightened back into spec. The captive bolt for the terminal clip required more tightening than I thought it would. Oh well, that's why they make these tools.

I'm happy (?) to hear that I'm not the only one with the issue or imagining things. I'll see if the problem went away tonight when I come home. If not, I'll unplug the battery, although I shouldn't really have to do that, should I? ...

I can't imagine what the poor, average consumer (who doesn't even know these forums exist) must be going through trying to get these issues solved by the service departments. Must be pretty frustrating...

you are correct you should not have to but unfortunately this is just the way it is. think about it the same as you would a computer any weird software problems just reboot

Thanks guys for all the replies! Good news is that tonight when I went down to start the Jeep, the HVAC was miraculously working fine again! Seems like the issue fixed itself overnight. Ufff.....

So that saves me from messing with the battery.

As a side note, other than this single glitch, I have been more than happy with my SFU! Have been driving it for almost a year now, and it still puts a grin on my face every single time :D

I booked an appointment to have the transmission flash done as well, to stay current;)

Ha - I wish I had known that there was a fix for this, because I had the opposite problem: When the climate control was set to 72 Auto the vehicle would blow out 53 degree air nonstop. It was only when you adjusted the temp up to MAX that it began to heat up, thus starting the endless cold/hot cycle.

I got the same "that's how they all are" - not from my dealership service guys - but from the regional tech reps. The supposed "software upgrade" in May did no good.

In the end it was too much for me, as I had three check engine lights, a bad DEF pump, got stranded in a blizzard at 250 miles on the ODO, etc. on my '14 Summit. You can't make this stuff up.

I really liked the vehicle but the climate control was the last straw, so they bought the vehicle back after much wrangling.

I had the same issue after getting this update lastweek. But the next day when I drove the Jeep the AC was working fine. They also updated the radio software and now I have the dreaded shaking back up camera image. Was not going to update the radio since I was not having any issues I was two updates behind but now I have to update to the latest one, since the dealer only updated to the next to last update..

Did you get the most recent radio update? I downloaded and installed mine myself and this update eliminated the back up camera stutter.
