Seat Exeo Air Conditioning Problem

I had a similar air conditioning issue with my Exeo. The rear vents were blowing warm air. Check the flap actuator for the rear ventilation system. The connection can become loose or corroded. Have you scanned the HVAC system for error codes?

Thanks for the tip! Do you recall where the flap actuator is located? Is it easily accessible?

The error code pointed to the rear ventilation flap actuator. I took it to a workshop. They confirmed it was a loose connection. If you're not experienced with HVAC repair, I'd recommend taking it to a professional.

Just to let you know, the shop confirmed a faulty connection to the rear ventilation flap actuator. Cost me 95€, but the air conditioning is working well again, and the errors are gone. Thanks for the assistance!
