If it is the only gauge not working, replace the temperature sending unit that is located on the motor.

On the right side of engine on cylinder head there should be a single wire onto a small pole. Try removing that wire and see if your temp guage goes all the way up to hot. If it does, then the problem is with the sensor. If it doesn't then there is a problem with the wire and/or the guage itself. Replacing the sensor is quite easy. You will need a 7/8's deep socket to remove and re install, note you will lose a little coolant so make sure to top up with 50/50 mix of antifreeze and water.

Fuel gauge sensor


Yes, the sending unit is in the tank. If you unplug the connector at the tank and ground the gauge's sender unit wire to metal, with key on, the dash gauge should jump to full or near full. This verifies the dash gauge is working properly, and the problem is with the sender unit in the tank. If the gauge doesn't move when grounded, then the gauge or wiring from tank to gauge is not correct.
Good luck.

1999 Mercury Mountaineer, heater/AC fan no longer blowing


I would check the fan first disconnect the electrical connectors on it and use a pair of home made jumper cables and run it from the battery. If it works move unto relay if it doesn't you've found the culprit.
Next check relay in the fuse box. Coolant tempertant switch(CTS) aka thermal switch and its circuit. CTS is usually located in the water jacket by the t-stat.

I've got a 91 Calais. The cooling fan isn't working. Replaced t-stat. Water is flowing now. Fuse is good. Is there a relay somewhere? Or a thermal switch for the fan?
