Last year I had an intermittent book symbol and Gilbertd kindly read/cleared it for me and IIRC it was for a stuck blend flap.
I now have a permanent book symbol and the passenger side vents seem intent on pumping out hot air regardless of what I set it to.
I'm guessing this means the flap is now properly stuck for whatever reason.
Is this something that is only fixable with a new blend motor or is it possible that it's stuck for some other reason and needs taking apart to be freed? I'm reluctant to buy a motor and not need it but at the same time I don't want to take it all apart and find I need a motor that I don't have.
