Heater blower

[TLC]

The Heater blower dosent work on my Rover 100
no responce from the switch.Its not the fuse so how do you test the blower or what else could it be.

Switch - worn out contacts
Motor - worn brushes, replace brushes. Occasionally new motors turn up, attached to new heater side cases
Thermal cut out (the so-called and wrongly named "otterstat") - corroded, clean with fine emery/wet & dry
Resistor coils broken. You can access that part from under the bonnet AFAIK so access is much easier than on Maestro/Montego, where the dash has to come out.
