Why does my Chevy Equinox fan keep running?
If your Chevy Equinox's fan keeps running, it could be due to a few common issues with the vehicle's cooling system. The fan is designed to turn on and off automatically to regulate the engine's temperature, but sometimes it may continue running even when the engine is cool.
Potential Causes of the Equinox Fan Running Continuously
There are several possible reasons why the Equinox fan might keep running:
- Faulty Coolant Temperature Sensor: The coolant temperature sensor monitors the engine's temperature and signals the fan to turn on and off accordingly. If this sensor is malfunctioning, it could be telling the fan to run continuously, even when the engine is cool.
- Thermostat Stuck Open: The thermostat is responsible for regulating the flow of coolant through the engine. If it gets stuck in the open position, it may cause the engine to stay cool, but the fan will keep running to try to maintain the temperature.
- Electrical Issue: There could be a problem with the wiring or relays that control the fan, causing it to stay powered on even when it shouldn't be.
- Cooling System Leak: A leak in the cooling system can cause the engine to overheat, triggering the fan to run continuously to try to cool it down.
If your Equinox's fan is running non-stop, it's best to have a mechanic diagnose the issue to determine the root cause and make the necessary repairs.
Troubleshooting Steps
To troubleshoot the fan issue on your Chevy Equinox, you can try the following steps:
- Check the coolant level and look for any signs of leaks in the cooling system.
- Use a diagnostic tool to check for any trouble codes related to the coolant temperature sensor or fan control system.
- Visually inspect the wiring and connections to the fan to ensure there are no issues.
- Have a mechanic perform a more thorough diagnosis, which may include testing the thermostat, coolant temperature sensor, and fan relay.
Addressing the underlying cause of the fan running continuously is important to prevent further damage to your Equinox's engine and cooling system. By following these troubleshooting steps, you can identify and resolve the issue, ensuring your vehicle's fan operates as intended.
How do I reset my blower fan?
How Do I Reset the Blower?
- Turn off the circuit breaker powering your HVAC system.
- Unscrew the blower cover.
- Give the blower time to cool down completely before proceeding.
- Push the reset button (typically a red button behind the blower motor).
Can a bad thermostat cause the fan to stay on?
Thermostat malfunction: The thermostat regulates the engine's temperature by controlling the flow of coolant. If the thermostat is stuck or not functioning correctly, the engine may overheat, triggering the fan to keep running.
Why is my cooling fan continuously running?
In a car, the cooling fan relay takes a signal from the car's computer and turns on or off the cooling fan. After many cycles of switching on and off, the relay will eventually fail, and when it fails, it could either be “stuck” at the closed or open position, leaving the fan permanently on or off.
Why does my Chevy Equinox keep running after I turn it off?
This can be caused by excessive carbon build-up in the combustion chambers or on the piston tops which when hot it'll act like glow plugs and will ignite a little bit of fuel getting into the cylinders. This is common on engines that run way too rich or have oil burning problems.
Why does my blower fan keep running?
Two problems that could cause your fan to run without stopping include: A bad fan limit switch that needs to be replaced. Bad thermostat wiring.
What do you do when your car fan won't turn off?
Shut the car off, verify the fan stays on. After 15 minutes if the fan is still running then unplug the PCM at the back of the engine compartment. If the fan goes off then you need to have the fan replaced. If the fan remains on then you need to replace the cooling fan assembly.
Why does the fan keep running after the car is turned off on a Chevy Equinox?
It is normal for the fan to stay running, sometimes for a few minutes after key off. This helps bring engine temps down and for the AC, cools the condenser which helps prevent high line pressure for extended periods of time.
Why is the fan still running when the car is off?
If your car's fan continues to run even after you've turned off the engine, it could indicate a problem with the car's cooling system. There are a few potential causes of this issue, including a faulty thermostat, a malfunctioning radiator fan relay, or a stuck coolant temperature sensor.
Why does my exhaust fan run all the time?
This is where a continuously operating exhaust fan comes in (also known as Mechanical Ventilation). A continuously operating exhaust fan provides a way to exhaust the stale air that builds up inside a home. The fan's airflow rate is set to achieve the number of air exchanges needed for your specific home.
Why is my cooling fan not shutting off?
If that happens, a simple problem has snowballed into a something worse. Essentially, there are two components that can stop functioning, triggering a failsafe mode that causes the fan to run continuously. The first is the fan relay, which due to age or corrosion will stop switching the fan on and off.
