PROBLEM: Wierd heater clicking noise?

[The Boosh!]

Hello!

When i turn on my heater for the windscreen and blowers, there is a really strange ticking/clicking noise. As I turn up the strength of the blowers it gets faster.

I don't really wanna take the dash off if I don't have to as its a PITA.

Any one know what the crack is?
