IMHO, I think a car with "Auto" temp in the A/C should be just that. I should be able to set it on a temp and the HVAC should keep the temp where you set it... like my other (ICE) cars I have owned through the years. I recently had 3M Crystalline tint installed which made a big difference in the heat build up in the car. In fact, I could tell the improvement because the fan didn't blow as fast in Automatic. LOL I suppose without the tint, the HVAC had to deal with higher amounts of heat energy which made the fan blow faster at a given temp. Now that the tint is installed the system does not have to work as hard to keep the temp at say 74 when it's 90 outside....less airflow. I guess one has to take the good with the bad.
