- Electrical Issues: Faulty or damaged wiring, a short circuit, or a malfunctioning fan relay can cause excessive current draw, leading to blown fuses.
- Fan Motor Issues: A seized or obstructed fan motor can put a strain on the relay, causing it to overheat and blow the fuse.
- Electrical Overload: If the fan relay switch is overloaded, such as when multiple high-current devices are drawing power from the same circuit, it can exceed the fuse's current-bearing capacity, resulting in blown fuses.
- Faulty Relay: A defective fan relay switch itself can also cause blown fuses if its internal components have failed or if it has become excessively worn out.
To resolve this issue, you'll need to diagnose the root cause of the blown fuses. This may require inspecting the electrical system, testing the fan motor and relay switch, and addressing any underlying problems to prevent further fuse damage. Consulting a qualified mechanic or auto electrician for accurate troubleshooting and repair is recommended.
