DATA Scrubbing...
So the wiring for the temp sensor was eaten by rodents (love that city life), That was fixed, new sensor installed......check engine light gone.......no other codes at all.....A/C still doesn't work.
. They tried everything but still nothing. They said the dealer might have to reset/reflash the computer or something? SMH.

Missing interior temperature data can be read as "-22°F" (instead of +70°F) without any associated code pointing you to that stealth error.
> In particular look at line pressure may be of interest.
> The module may need to be reset after repair.
> Another thing to be aware of.... this module is built with solderless connectors.
This promotes marginal glitchy operations. Soldering these contacts is a simple 5mn DIY fix.

Putting aside the fact that I can't figure out how the hell the windshield defroster refuses to blow anything but 90 degree air (before today, all the time), the A/C decided to stop blowing cold air on the hottest day of the year. I drove it this morning, all was good and then all of the sudden tonight I don't have "hot" air blowing but it damn sure isn't cold either.
