Hi, I was on the way back on a road trip yesterday on the highway. Suddenly, I noticed the ac started getting warmer and when I went on my climate the ac light was flashing. I went home and today checked for the ac code. It gave me 19. I tried disconnecting the battery and reconnecting, same result, feels like the compressor kicks on for a second and then shuts out. I saw somewhere it could be related to the rear temp control sensor, which I do remember for months only blows warm air out the bottom for the rear seats and the rear climate control settings are unresponsive. But that's been happening for a while so I don't know why the ac went out now. Any help?
