Mk1 Aero 8. Having just returned from a 600 mile round trip in the mid 20c , I have discovered that despite roof off (of course,) and air con on (which blows ice cold), at 80mph I have hot air travelling up the steering column and blowing straight at my inner "knee" . Whilst this is quite pleasant in the winter, it makes summer driving a little hotter than I would like . Has anyone had any experience of this and is there any quick fixes ? I am sure it is just air being forced from the engine bay, but would love to find a way of minimising it ?
