The inside/outside flap or door which sits above the fan in the firewall is stuck in the 'recirc' position...easily seen by removing the pollen filter, but can't be accessed from up there.
Is there a sraightforward fix for this...or do I face a life of breathing stale air? It's too cold at the moment to drive with the windows down.
As always, comments and/or advice will be welcomed.
