Cooling (radiator) fan not working, '05 ZT 190

Afternoon all. As I have mentioned elsewhere on this rather excellent forum I have recently acquired an '05 ZT 190. It has had little use for a couple of years, maybe that's why the air con doesn't work.

So, I searched the forum and read up on non-working air con, not a five minute job! I went through Jules's test procedure, cooling fan does not work at all. Compressor clutch can be made to engage by bridging the relay contacts.

This then means that when the engine starts too get hot the cooling fan will not cut in. Would that be right? The temperature gauge stays steady showing no signs of an overheat. If the engine overheated would this not show on the gauge? Or a warning light/message?

Also there is no resistor fitted, does this fitment depend on the type of fan, 2 or 3 speed? If I need a new cooling fan, whats available?
