My heat doesn’t work unless I have the setting on “HI” (which is over 81 degrees). Then it blows a lot of very hot air. I moved the temp down to 78 degrees and get cool air! I’ve brought the car in, again, for this issue and just got it back with no solution “the diagnostics on the car are all fine”. Has anyone else had any issues with the heat? So I have cold air, cooler air, and extremely hot air! This is very upsetting for an expensive car and such a seemingly minor issue.
