Where is the fan control relay located?
The fan relay is usually located near the bottom of the engine compartment on a metal frame member. The metal acts as a heat sink to keep the fan relay cool. So, unplug the connector at the relay and repeat the check for power.
What causes cooling fan relay failure?
Possible Causes of a Bad Cooling Fan Relay Common causes for relays failing to operate might be: Failure of the computer, temperature switch, or relay control module that turns the relay on or off. Damage caused by changing between circuits with different speeds and electrical load.
Where is the fan module located?
The cooling fan control module in your vehicle is located at the front left of the engine compartment next to the radiator.
Where is the cooling fan control module?
The fan control module can be located in a variety of places on the vehicle. The most common is on the radiator fan and condenser fan assembly as shown above. Other possible places are along the firewall of the vehicle or even under the dash.
Does radiator fan come on with AC?
The condenser fan (if it has a dedicated fan) or the radiator fan most always comes in (with AC on) when the compressor discharge pressure (or, alternatively, the liquid line one; look for where a sensor or a switch is located on the high pressure line) rises over an operative threshold.
Does PCM control cooling fan?
The PCM controls fan operation; it uses the signal from the ECT or engine coolant temperature sensor. This sensor senses the temperature of the engine’s coolant and sends a variable voltage signal to the PCM.
What is the fan control module?
An A/C fan control module helps to control the blower that supplies air to the cabin of a vehicle, as well as the cooling fans. The module helps to make sure that the cool air that is produced within the A/C system of a car is blown into the cabin.
What is a fan module?
As is implied by the name, a cooling fan module is a device in your car that controls the temperatures in the engine by regulating the speeds at which the fan motor rotates. This creates a cooling effect in the engine, preventing it from overheating.
At what temperature should my cooling fan come on?
about 200 degrees Fahrenheit
Your radiator fan should kick in at about 200 degrees Fahrenheit. If you notice your vehicle is overheating or at the very least running hotter than it normally does, listen for the fan to see if you can hear it.
