1. Take your fans out. test them by using the battery to connect directly to them. If they spin then you know its not your fans.
2. Your coolant temp *SWITCH not the sensor could be faulty also. Take a paper clip and short the two wires together. Your fans should come on. If they dont then something else is going on and you should check your relays per below.
3. Take your relay out and make a external hookup to it. 30 to ground, 85 to +12V, 87 will be your output. When you put +12V on 86 you should get +12V on 87. This is assumning the relay is a SPDT.
