That fixed it. Took battery cover off, reached into fan chmaber and slowly turned it by finger until I got to a point where a small leaf was stuck between the blades. Will post pics later.
Made sure the ignition was off (keys in my pocket) before I stuck my hand in the fan!
I'm suprised there's not a mesh screen to stop debris entering the fan. Maybe one for a future project.
