Is it needing re charged? or check passenger footwell for water under the carpet as the heater matrix has may be failed.

[peter thomson]

Have you checked the plugs on the heater control unit or tried another control unit

.if matrix on way out would that stop fan blowing ..tried new control unit

No heater matrix wouldn't affect fan blowing! Unless it leaked water on corresponding electric. But that's not very likely. Can you still feel heat up behind dash.
