Good Afternoon all

i have just bought a S reg ford focus and there is no internal heating working, i have replaced a 30 amp fuse in the engine bay and nothing.

there is no sound of a fan working internally, i have heard this is a common problem, i am not sure where to start as i do not want to pay the cost of a dealer.

any one had this problem that could provide a step by step guide to resolving the issue would be a new best friend.

diagrams would be fantastic also.

thank you for any help in advance
