1. Temperature Sensor: The temperature sensor may be faulty, causing the engine to overheat and trigger the cooling fan to stop working.
2. Wiring Issue: There may be a break in the wiring or a loose connection between the temperature sensor and the cooling fan.
3. Cooling Fan Motor: The cooling fan motor itself could be faulty or experiencing internal damage.
4. Cooling Fan Relay: The cooling fan relay controls power supply to the cooling fan. If the relay is faulty, the cooling fan won't receive power.
Here's what you can do to troubleshoot and fix the issue:
1. Check the Temperature Sensor: Disconnect the temperature sensor and check for continuity using a multimeter. If there's no continuity, the sensor may need replacement.
2. Inspect the Wiring: Thoroughly examine the wiring between the temperature sensor and the cooling fan for breaks, shorts, or loose connections. Repair or replace any damaged wires.
3. Test the Cooling Fan Motor: Disconnect the cooling fan connector and apply direct power to the fan terminals. If the cooling fan doesn't spin, it's likely faulty and requires replacement.
4. Check the Cooling Fan Relay: Locate the cooling fan relay in the fuse box. Swap the relay with another identical relay to determine if the original one is faulty.
If the issue persists after checking and fixing these possible causes, it's recommended to consult with a qualified mechanic for further diagnostics and repairs.
Before attempting any electrical work, ensure you disconnect the battery's negative terminal to prevent potential short circuits and electrical shocks.
