If you go to the parts store they can find the right part for you, even a wire connector. This sounds like the temperature sending unit.

Sounds like you're looking for the coolant temperature sensor pigtail. I'm assuming that you have the 3.8L V6 engine (3800 Series II). Unplug the coolant temperature sensor and start the engine. The coolant temperature sensor is just below the thermostat. The check engine light will come on because the sensor is unplugged. Ignore it. Your radiator cooling fans should both come on at high speed immediately. If so you can rule out the fan relays, PCM, fan motors, and any bad connections. If the fans do not come on you'll have to check for a bad connection, bad fan motor(s), or bad relay(s). Before poking around the fan motors disconnect the negative (-) battery cable. You don't want the fans to start unexpectedly!! About the relays, there's 3. Two 4 pin relays which are for each fan motor individually and one 5 pin relay which is for both fans together. The 5 pin relay is called the high speed relay. HTH. -Jim

I have replaced all three relays and have changed the coolant sensor and pigtail all tighter and I made sure the pigtail was connected right in to the wiring that came off the blue and white sensor that is covered up by wiring cover things and made sure the wires are touching and all the fuses and relay are brand new I cant get them to come on and also that it gets hallway mark and wont stay in cooler

Unfortunately I can't do that. I'm sorry but forum rules don't allow that. Have you tested the fan motors themselves? For testing purposes only, wire each motor, individually, to the battery or other 12 volt DC power source. They should definitely run then. If not the motor(s) are bad. HTH. -Jim
