Heater blower fail

Hi ( hope ,as a relative newbie , I'm in the right place here ....)
Just replaced a duff heater blower resistor, which wasn't as hard as I thought (& as it aint stopped raining up north for a while, I've not checked the fuse yet . )
But ... Its not fixed the problem , anyone else had similar problems ?

The fan should have still worked at no.4, even if all 3 resistors had failed.

It isn't uncommon for the actual blower to fail. IIRC they are actually easier to replace than the resistors.

But I would use a multimeter to check the power going to the fan just in case the problem is elsewhere
