‘97 Dodge Neon, Cooling Fan Sensor
Q: How do I find the Fan Sensor on the motor of my car? I have a ‘97 Dodge Neon.
A: The cooling fan system on your vehicle doesn’t have a dedicated fan senor. The coolant fan is activated by a relay that is computer controlled. The vehicle’s computer receives coolant temperature information from the engine coolant sensor. This sensor, is really two sensors in one. One part is used for the temperature display and warning light on the instrument panel. The other part of the sensor reports to the computer. Based on programmed information the computer will activate the cooling fan relay which turns on the fan. The computer will also turn on the cooling fan if it sees the A/C system activated as well. If your cooling fan isn’t working I would first suggest checking the 30 amp cooling fuse located in the power distribution center. If the fuse is okay then check the cooling fan relay. I thought I’d check on the location of the cooling fan relay for you when I found a cooling fan relay recall on your vehicle. ALLDATA Information systems shows a recall #7691 for Dodge and Plymouth Neons built in ’97 and ’98. This condition affected about 45k vehicles. The problem was that the cooling fan relay would not turn on the cooling fan, resulting in an overheated engine. You should check to see if your vehicle was affected by this recall. If this is the case, the repairs will be performed at no cost to the vehicle owner even if you’re not the original owner.
