1. Faulty blower motor. If the blower motor is faulty, it can draw too much current and blow the fuse. To check the blower motor, disconnect it from the power supply and test it with a multimeter. If the blower motor is faulty, replace it with a new one.
2. Dirty blower motor. A dirty blower motor can also cause the fuse to blow. To clean the blower motor, remove it from the vehicle and vacuum it out. You can also use a brush to remove any dirt or debris from the motor.
3. Bad blower motor resistor. The blower motor resistor is a component that controls the speed of the blower motor. If the blower motor resistor is faulty, it can cause the fuse to blow. To check the blower motor resistor, disconnect it from the power supply and test it with a multimeter. If the blower motor resistor is faulty, replace it with a new one.
4. Electrical short in the wiring. If there is an electrical short in the wiring, it can also cause the fuse to blow. To check for an electrical short, use a multimeter to test the voltage at different points in the circuit. If you find a voltage difference, there may be an electrical short. To repair the wiring harness, fix the electrical short that you find.
By following these steps, you can troubleshoot and fix the problem with your Neon's blower motor fuse blowing.
