The module that runs the HVAC system. Tells the AC clutch when to kick in and other things like that. If you were trying to ask where it is I couldn’t tell you.

Having similar issues. Compressor was replaced last year and I’ve just replaced it again. Compressor comes on then shuts off. New HVAC Module just installed as well (second hand) but no improvement. Two different shops are at a loss now. I’ve got one other shop to try but hoping to learn something here to help point them in the right direction.

The owners manual says to run the AC weekly. Not sure if any of the failures could have been prevented by usage but its an interesting maintenance item.
Houston, TX so yeah it gets used 11 mos out of the year

Yeah, plenty of use there. In Vegas my AC seemed worthless. But realistically I'd probably die on the freeway in traffic without it. The pavement gets super hot and all the heat its partitioned by jersey barriers and then the slow hot cars along with the blistering heat of the sun. It his 120F each year except this year it hasn't been that hot for whatever reason. This year has been a nice break.
