Just bought this motor, my first Ford in 30 years!! Seemed OK on test drive, 90,000 on the clock, but private sale, so no guarantee with it. On the ventilation fan, the lowest 2 speeds do not work, and even on the highest setting there does not seem to be much 'draught' from the air-vents. Also, the Aircon switches on whenever the ignition is turned on, irrespective of it being previously switched off. Any comment or advice would be much appreciated, thank you all.
