I've always assumed that the blower was there for keeping the injectors
cool after you shut the car off(ie, no air circulating in engine
compartment, injectors right next to the toasty engine block, etc.)
I don't believe it's ever run with the car on...could be wrong though.

You can check the thermostat...I know that you can check the turbo coolant
pump by shorting out two contacts on one of the thermoswitches(this makes
for a handy way to cool down the engine quickly if you want to work on it!)
and there is probably a similar test procedure to check the wiring etc...

(BTW, my references are to a 87 5kcst)
