AC blows hot on rare occasions

[Finehomebuilder]

I’ve searched previous posts and not found my particular issue. Living in the south, AC is needed. On very rare occasions when in manual or auto, AC blows really hot. I’ve tried turning on key but not starting with no effect. When it happens I turn off, wait and try again. No effect. Next day, cools great. I have it at dealer now for the second time and they can’t get it to happen.
Any suggestions for them to explore would be appreciated.
Also getting door buttons done, but have not had a problem with them. Also software update.
I’ll be bringing our second one to them next for second round passenger door seal and button's. No software update for this earlier one.
Otherwise, we are really enjoying them both.
Thanks!

I had that issue, and the only fix was to remove the AC fuses from the fuse block under the rear seat. Let it sit for a few minutes and reinstall the fuses. Quite inconvenient, and a frankly dangerous issue they should take more serious. It was 107 F when it last happened, and I was in a remote area with a pregnant woman as a passenger. I told the dealer and they didn't seem all that concerned. Just stating they have heard of the issue, but never seen it in person.

Thanks for the fuse info. Glad to hear that at least they have heard of it. I’m not sure it will be addressed.

Could you please send a picture for identification of the right fuse?

I have this same issue...dealer says they know the issue but don't know what causes this or how to fix it. I have to let it sit 10 or 15 min and it seems to correct itself but would sure like a real fix.

I had it happen to me yesterday. It was a nice 100 degrees here in Pasadena and I was rushing to a meeting. First time it has happened since the software update several months ago.

I did figure out a new fix that worked while driving. I actually turned auto off, turned the fan to the first setting, rotated to full heat and then went through all of the air direction positions and waited for the air to get redirected. Then I rotated everything to the left, hit auto again, and turned the temp to about 68 degrees. Al of a sudden it started blowing ice cold air.

I think the computer gets out of sync with the blender valves and this seemed to reset it. Hoping for someone else to validate the procedure.
