V90 AC and rear ventilation flap issue

Hey, I'm having a weird issue with my 2019 Volvo V90 diesel. It's done 111131 km. Basically, the air conditioning isn't cooling like it used to. I ran a scan and it's showing an error related to the rear ventilation flap. I also noticed the climate control seems a bit off, like the air isn't being distributed properly. Could this be the ventilation flap causing all these problems, or am I barking up the wrong tree? Feels like when your house's central air has a blocked vent – everything just gets wonky!

Sounds familiar! I had a similar problem with my old Opel Astra. The error code pointed to a flap motor, but it turned out to be a faulty connector. Have you checked the wiring and plug connection to the rear ventilation flap motor? That's often the culprit.

Interesting! So, you're saying even if the error points to the flap itself, it might just be a loose wire? I'm not super mechanically inclined, but where exactly would I find this connector to check? Is it something easily accessible, or do I need to dismantle half the car?

Yep, a bad connection can throw off the whole system, just like a loose lightbulb can cause a short. On my Astra, it was a pain to get to, but it may be easier on the Volvo. Given your symptoms and the error code, it’s probably worth having a workshop take a look. I ended up paying around 80€ for them to fix the connection.

Okay, that's super helpful. I think I'll take your advice and get it checked out by a professional. Knowing it might just be a connection issue and a potentially cheap fix (the estimate is 95€) makes me feel a lot better! Thanks for the insight!
