The electric fan is not designed to only turn on when the air conditioner is turned on; instead, it has a temperature control. When the Jeep’s temperature rises beyond a certain threshold (I believe it is 195 or 205 degrees, but someone please correct me if I am incorrect), the electric fan is activated. When the temperature falls below a specified threshold, it shuts down.
- The electric fan should turn on anytime the A/C compressor is turned on, and it will also turn on if the engine temperature rises to a certain level (I’m not sure what that level is). Examine your electric fan to see whether the motor has seized or whether the fuse has blown.

When should my electric fan come on?
Fan Trigger is a term that refers to the act of triggering a fan’s interest in something. The fan should turn on when the engine temperature reaches a certain level. It will also switch off the fan once the engine temperature has dropped to less than 200 degrees. A part known as the radiator fan switch, sometimes known as the temperature fan switch, may have come across your radar. This is connected to a thermostat and functions in the same way as your home’s HVAC system.
What temperature does a Jeep fan turn on?
If you trust the claimed temperatures, the thermostat will open at 194 degrees. The specification is 190.
How do you check the clutch fan on a Jeep XJ?
Test the fan clutch by heating the engine to working temperature, turning it off, then spinning the fan as hard as you can; if the fan can turn one complete circle or more, it is time to replace the clutch.
Why are my radiator fans not turning on?
It’s fortunate that the most typical causes for a radiator fan not operating are caused by a blown fuse, a defective relay, or a damaged wire. It can also be caused by a malfunctioning coolant temperature sensor, a low coolant level, or even by damage to the fan motor itself.
Why is my engine fan coming on?
When a radiator fan fails to operate, the most common causes are fortunately simple ones such as an overheated fuse, a defective relay, or an uncoordinated wire. Alternatively, a malfunctioning coolant temperature sensor, a low coolant level, or even a broken fan may be responsible for this issue.
How can I tell if my radiator fan is working?
It’s fortunate that the most typical causes for a radiator fan not operating are due to a blown fuse, a defective relay, or a damaged wire. It can also be caused by a malfunctioning coolant temperature sensor, a low coolant level, or even damage to the fan itself.
Is the radiator fan always supposed to be running?
The fan should not run continuously, but rather at a specified temperature (the precise value varies from car to automobile because various engines operate at different temperatures) in order to cool the engine down before it becomes dangerously hot. The fan should not be turned on all of the time.
Should radiator fan turn on when AC is off?
The AC controls may activate the fan from a location in the control circuit following the typical temperature sensor, ensuring that everything is in working order when the AC is turned on. When the air conditioner is running, the fan may also be running continually.
How do I know if my clutch fan is bad on my Jeep?
To establish the diagnosis, begin with this straightforward procedure: On an engine that hasn’t been started yet that day, crank the fan as hard as you possibly can. Any time the fan revolves more than five times, you may be certain that the clutch is faulty. According on the temperature of the room, you should feel some resistance, and the fan may spin up to three times more than once.
Where is the fan relay on a Jeep Cherokee?
On the 2004 Jeep Grand Cherokee, the PDC (power distribution center) is located beneath the hood on the passenger side and has two fan relays (one for high speed and one for low speed). An engine that runs hot or overheats is one of the first symptoms that might be related with a defective or malfunctioning cooling fan relay.
Where is the fan relay?
This component is normally found towards the bottom of the engine compartment on a metal frame member, which serves as a relay. The metal functions as a heat sink, allowing the fan relay to operate at a comfortable temperature.
Where is the coolant sensor on a 1997 Jeep Grand Cherokee?
Coolant temperature sensor (5.2 L) located on the intake manifold, close to the thermostat housing.
