Hi there 964 heater working , temp good hot or cold blows well but wont blow onto windscreen .... I can hear it blowing away behind the dash but something not opening or obstructing it from blowing onto windscreen... any idears??? Thanx
The servo motors are a common failure point - There are 5 of them and I've had two go in my time. The airflow to the windscreen vents is controlled by one of these so that seems the obvious candidate. They're not cheap, if I remember it correctly.
