Unplug the connector at the fans, use a test light and see if any power is getting to the fans. Turn on the a/c, fan should start up with the a/c, if no power at connector, let me know, if it gets power, the fan is no good. You can also run a fused wire from the battery positive terminal, and a ground to the negative terminal, fan should run.

Right next to the thermostat on the back of the engine there are two sensors, one of them controls the fan. Depends how hot the engine is if the fan runs a bit or not!
