At approx. 100deg C switch should close. Multimeter will tell you if it does.

service book is in the downloads section, has details on testing fan switch.

if you take the one wire off it and ground it the fan should come on.. if it doesnt then you have a problem with fan / fuse rather as well as possible fan switch

In more detail, remove the connector from thermo switch, with ign on, earth onto rad - does the fan come on? Now short to the engine/frame, does it come on?

Most fan issues are blown fuse as the fan has stuck from lack of use or a bad earth.
