Blowers not working - Volvo S40/v50 (2004on)

[Petrolhead_Rich]

Bit of history, everything working fine then the car has been stood for about 8 months, entire engine out etc to resolve separate issues (replace Turbo etc) and now the fan doesn't work for the blowers.

Any ideas?

It is possible I have disturbed a connection under the bonnet, but havn't touched anything inside the car/behind the dashboard?!
