chaces of this are about 1000 - 1. Thermostats either open, or they stick.
Not saying the thermostat is not faulty, id just say you get your fan working 1st, then see what happens.
1. Unplug the fan thermo-time switch on the thermostat housing with the key on, if the fan operates when you unplug it, replace the switch.
2. If not, then apply 12v to the fan itself to see if the fans faulty.
3. If not, check the relay,
4. if thats fine, theres a faulty connection somewere.
