Thanks for that, I'll check tomorrow. No way I'm going outside now as it's p*ssing down! Will let you know.

I've actually just dashed out in the pouring rain to have a look and it appears to have the blower but clearly doesn't work! Are they easy to source or can you get uprated ones cheaply?

There isn't any noise at all when the heater switch is used. It doesn't seem to heat up at all which makes things difficult to say the least! Can't see out of the screen most of the time due to condensation...or frost!

Probably an easy yes no answer- Is it easy to fit heating/heater fan to a series 3? If yes what would I need? Thanks
