OTA Update GM N22-238206 HVAC Quirk

[SmokeyJoe]

Installed this on OTA on 5/19/23 in my 2022 Tahoe LT. Ever since installing, when I start up, the blower goes on high (it is pretty hot here already). That is expected with the system in "Auto". Before I can get out of the garage, the front blower goes very low, the rear blower is running at max. After a few minutes of driving, the system then shifts back to on high for both systems until the interior cools down and normal operation resumes.

In order to live with this strange behavior, I can and do, manually turn up the blower speed and after a few minutes press the "Auto" and everything is normal again.

Is it just me?

Not just you. I think that it is related to this issue:

22 Tahoe/Google Speech error

Every time I start my car I have an error come up on my 2022 Chevy Tahoe infotainment screen. It says “Speech Services by Google…For your safety this utility isn’t available while driving. To continue wait until you’re in park.” How do I get rid of this? I have tried shutting off notifications...

I am experiencing the exact same issue. My work around is the same as yours... as soon as the blower goes to low, I manually crank it up and then reenable the auto climate control. This all started immediately after I updated the software.

Are you guys seeing the google speech message pop in the post I referenced above up as well? I am taking mine in tomorrow to try to get a fresh software install, not OTA update...

Not all the time but every once in awhile. Even without that google speech message, the HVAC still acts up. Please let us know what end up happening with the fresh install.

I got an infotainment update at the dealer (to version Y168) yesterday. I now have these odd AC quirks, without any speech error messages.

Well despite scheduling in advance for them to do this, they told me that I would have to leave the vehicle with them for 3 days for them to "diagnose" before doing a fresh install of the software. I cant leave it with them now so will have to push out a bit. I have 35k miles right now, so I will need to do it soon, as they said that the "software" is only covered up to 3/36... Big dealerships suck...

I noticed the same thing the last couple weeks after the OTA update. I tried cranking the temp down in auto but it wouldn’t come back so same as you I did the manual back to auto. Super annoying especially in the heat. I noticed this behavior is similar to when your on a call using blue tooth the air slows down a bit to quite the cabin, it’s as if something is triggering that action and the air goes down.

Isn’t there a saying in the software world that for every few bugs fixed, a new one is created?

Same issue for me with the A/C after the update.
