Where is the fan relay located?
The cooling fan control module in your vehicle is located at the front left of the engine compartment next to the radiator.
How do I know if my fan relay is bad?
Symptoms of a Bad or Failing Cooling Fan Relay
- Engine running hot. One of the first symptoms commonly associated with a bad or failing cooling fan relay is an engine that runs hot or overheats.
- Cooling fans do not function. Non-functional cooling fans are another common symptom of a potential problem with the cooling fan relay.
- Cooling fans stay on at all times.
How do you test a cooling fan relay?
The quickest way to tell whether or not the electric fan(s) are working is to start the engine; let it reach normal operating temperature and then turn the A/C on. The cooling fan in the engine compartment should turn on to pull air through the radiator and A/C condenser.
Where is the condenser fan relay?
Step 1: Locate the condenser fan relay.
In most vehicles, this relay is located in the power distribution center or underhood junction box. A few vehicles have this relay mounted on a fender apron or on the firewall.
How do I know if my fan clutch is bad?
Symptoms of a Bad or Failing Fan Clutch
- Vehicle overheating. One of the first symptoms that is commonly associated with a bad or failing fan clutch is an overheating engine.
- Excessively loud cooling fans. Another common symptom of a faulty fan clutch is excessively loud cooling fans.
- Decrease in power, acceleration, and fuel efficiency.
Is there a fuse for the radiator fan?
If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.
What happens when a relay goes bad?
If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. As a result, your engine won’t turn over – no matter how many times you turn the key. A faulty relay often produces an audible clicking sound when you turn your car.
Why is my engine fan always on?
It is possible that this problem of your car’s fans constantly running is some sort of mechanical or electrical error from a poor sensor or other component. There are temperature sensors and some cars have separate sensors for the gauge itself. The fan can be shut off when the engine temperature warrants.
Should radiator fan run all time?
An electric fan SHOULD NOT run all the time. The fan turning on is normal and a consequence of the hot coolant, not a cause. The coolant may not be moving due to a water pump problem, blockage in the radiator or hoses, or a stuck valve, i.e., the “thermostat” in the coolant line.
What tells the cooling fan to come on?
The engine temperature should trigger the fan to turn on. It will also turn the fan off once the engine has cooled to under 200 degrees. You may have heard of a part called the radiator fan switch or temperature fan switch. This is linked to a thermostat and works much like your home’s HVAC system.
What causes cooling fans not to come on?
Six things may prevent an electric cooling fan from coming on: Defective temperature switch, coolant sensor or other sensor. Engine thermostat is stuck OPEN (engine never gets hot enough to turn on the fan) Faulty fan relay.
How do you test a fan control module?
To test a fan motor, unplug the electrical connector at the motor and use fused jumper wires to connect battery power and ground directly to the fan. If the fan does not operate, replace the motor.
What does a condenser fan do in a car?
The AC condenser fan’s job is to keep the condenser cool so that it can keep converting gas into liquid, and overall, keep the AC system working as it should. If the condenser fan fails, your car will likely display a few warning signs.
What controls the condenser cooling fan?
The condenser fan relay is the electronic relay that controls the power to the AC condenser cooling fan. The AC condenser is designed to cool down and condense incoming refrigerant vapor into cooled liquid and uses the fan to help keep it cool. The fan’s power is controlled by the condenser fan relay.
What is the function of condenser fan?
The condenser fan motor is what runs to turn the fan blades and blow air across the condenser coil, where it cools the refrigerant from a hot gas into a liquid. Maintaining the condenser fan motor can help to prolong the life of the AC compressor.
