i have had my 2019 jeep compass to the dealer twice this week for a check engine light. The first time, they said there was no codes and there was no problem they could find. Light came on approx. 24 hours later. The second time still no codes, but they did replace the blend door actuator as the heater controls were not registering on my screen. Light stayed off overnight and is now back on and my heater controls are still not registering on the computer screen as they did the second time. I am back at the dealer again, but they seem to have no idea what's wrong. Any ideas??
