Windcreen demister fixed

I had an issue where the hvac system was stuck in blowing just to the face vents.

The fault was the no.1 servo for the vent control, dash out job to get to but not difficult. Having removed the old servo I took it to bits to see what the problem was. Inside there is a large gear with tracks on it that run on metal pins like a record player. I could see no visible fault with this but continuity testing proved it was defective. removing the gear the motor would work continuously proving that the motor was fine. All working now though, A new servo was £110 delivered from Japan as non in stock in UK.
