Hi guys advice please
Getting no hot or cold air to either footwell, screen and facial vents all ok and blower working and heat ok.
When the problem first started, if I turned the ignition off and on I would get air to the footwell, and sometimes it would just work ok as it should when I pressed the footwell button on the hevac , sometimes if I hit the footwell button nothing would happen for about 6 miles then it would just start working ok. The only other thing is that even though I have the footwell button illuminated on the hevac the air still comes out of the screen vents?

Bummer. Sounds like the flap position blend motor. Have you got the open book symbol with an explanation mark on the HEVAC panel? If it is that one which goes it's going to be a tight job to do. It lives just to the left of the steering wheel on the heater box. It's very cramped just there. I've done the nearside blend motor and that's the easy one and it still made me swear.
