e39 heater stopped working!

[Scamp's Walker]

Car was fine yesterday! Got in it this evening no fan sound when heater switched on. Air con pumpstarts when a/c button pressed. Changed fuse for heater/ rear window demister but have no replacement fuse to try in larger resistance fuse 45/46.

Any ideas...could it be that mythical beast....the hedgehog?

Hedgehog is easy to change and likely to be the problem. Some photos of changing mine here
