Well I don't think the customers want to have it come to that, but it might. Be better if FCA stepped up and made some changes that would require a TSB for some vehicles and some minor modifications that are factory authorized.I seriously doubt FCA is afraid of a class-action lawsuit over air vent temperatures of say 52 instead of 42. There's no guarantee on how effectively air conditioning works - so long as it it is removing humidity and reducing the cabin temperature relative to that of outside, it is perfectly operational. "Cold" when it comes to AC is largely subjective.
I think in the mobile AC engineering field, cold is not really subjective in the technical sense, throughout the decades most
engineers seem to consider between 38-42 optimal temperature coming out of the driver's side center vent with
the following. AC on max, recirculate on, fan on high, and car parked outside in ambient temp of 90 F under a shaded area. That is pretty standard and has been I would guess for at least 40-50 years now, at least in the USA and Canada.
