How To Test Cooling Fan Relay - How To Check A Fan Relay : (most likely failure and most difficult) if the radiator fan control module has failed you will need to replace it with a new one there is no way to repair it.. The cooling fan relay takes the low voltage signal and internally switches the relay on to allow battery voltage to be supplied to the radiator cooling fan. If it is getting 12+ volts, the fan should be coming on. Heat/ defrost fan fuse number 7 inside drivers dash fuse box. The engine may also overheat, if the fan speed fails to increase when additional cooling is needed. Bypassing the radiator fan switch.
If the fan doesn't engage, there may be something wrong with the cooling fan relay. Let it reach normal operating temperature and then turn the a/c on. The headlamp module must be removed to access the relay. But if it's not, which means the fan has gone bad. The fans are driven by electric motors that attach to the fan shroud.
Dose anyone one know how to test the fan relay? To replace the module, the radiator fan relay is located below the left front headlamp module. After confirming that the radiator fan relay is getting juice (test 1), the next step is to jumper circuits 1 and 2 with a jumper wire to see if the radiator fan motor comes on. Testing a cooling fan relay the easiest way to know whether your relay is causing trouble is to replace it with another relay in your vehicle you know is working fine. Switch on the a/c and turn it down to the coldest setting. The cooling fan relay takes the low voltage signal and internally switches the relay on to allow battery voltage to be supplied to the radiator cooling fan.

This electromagnet is turn on the burner and slowly increase the water temperature.
Let it reach normal operating temperature and then turn the a/c on. This controller does not have diagnostic capabilities. The engine may also overheat, if the fan speed fails to increase when additional cooling is needed. Testing the fan relay is easy, the hardest part is getting to it, since jeep in all its wisdom, located the fan relay behind the right side (passenger side) of the front bumper and you'll probably have to remove it to access it. Coolant fc (fan control) control module to control the electric cooling fan, it is located above the electric fan. I think that on hot days you will need at least min. Look at the power center under the hood for a similar relay that won't interfere with the correct operation of your engine if swapped, like a window or wiper relay. The headlamp module must be removed to access the relay. Cooling fans do not function. Bypassing the low speed fan motor relay. The cooling fan in the engine compartment should turn on to pull air through the radiator and a/c condenser. How to install replace ac heater fan speed resistor chrysler pacifica 04. Testing the amperage draw of the low speed radiator fan motor.
(most likely failure and most difficult) if the radiator fan control module has failed you will need to replace it with a new one there is no way to repair it. The quickest way to tell whether or not the electric fan (s) are working is to start the engine; The engine may also overheat, if the fan speed fails to increase when additional cooling is needed. Look at the power center under the hood for a similar relay that won't interfere with the correct operation of your engine if swapped, like a window or wiper relay. Because, it can allow the engine to overheat.
Bypassing the high speed fan. Set the ohmmeter to the lowest range. The cooling fan relay is the relay that controls the engine's cooling fans. One of the most common symptoms of a fan clutch on the outs is an inability to properly cool the air circulating through the vehicle. An electric fan under the hood can start up even when the engine is not running and can injure you. This video from ratchets and wrenches is a phenomenal resource on how to properly diagnose a wiring problem. Making sure both fan motor relays are getting 12 volts. I think that on hot days you will need at least min.
If the fan doesn't engage, there may be something wrong with the cooling fan relay.
Where to buy the radiator fan assembly and save. Dose anyone one know how to test the fan relay? If it fails to cool down after several minutes, or seems to be emitting unusually warm air, there could be a problem. Then, connect the meter's probes to the fan switch relay's two power terminals. How to install replace ac heater fan speed resistor chrysler pacifica 04. The fan may work but it only runs at low speed. Ford focus cooling fan resistor test Check the relay for the fans: If the fan doesn't engage, there may be something wrong with the cooling fan relay. The easiest method is to start the engine and then turn on the air conditioning. Because, it can allow the engine to overheat. The cooling fan relay takes the low voltage signal and internally switches the relay on to allow battery voltage to be supplied to the radiator cooling fan.

Testing the fan relay is easy, the hardest part is getting to it, since jeep in all its wisdom, located the fan relay behind the right side (passenger side) of the front bumper and you'll probably have to remove it to access it. Connect one of the ohmmeter probes to one of the thermostat terminals and connect the other probe to the second thermostat terminal. Coolant fc (fan control) control module to control the electric cooling fan, it is located above the electric fan. If the relay fails, it will be unable to supply power to.
By using a lower voltage signal to control the relay, there is less stress on the rest of the wiring and charging system. If it is getting 12+ volts, the fan should be coming on. When the correct parameters are met, a temperature switch or the computer will activate the relay, which will allow power to the fans. An electric fan under the hood can start up even when the engine is not running and can injure you. Use these tips to learn how to test a 4 terminal relay. This controller does not have diagnostic capabilities. If the fan doesn't engage, there may be something wrong with the cooling fan relay. You can test the voltage going from the fan relay to the fan itself.
But if it's not, which means the fan has gone bad.
