What's the matter if the car's starter motor doesn't respond?

It is caused by the wear of the starter motor's carbon brushes. Here are the specific details: 1. Using tools: Find a long-handled screwdriver or tire wrench from the car's tool kit and tap the starter motor or nearby parts a few times. Be careful not to hit the motor's live wire terminal to avoid a short circuit. The spring allows the starter motor's carbon brushes to press against the rotor electrode under external vibration. After tapping a few times, try restarting the motor; most attempts will succeed. 3. Push-starting the car: The driver should turn the ignition switch to the ON position (all functional indicators on the dashboard will light up), press and hold the clutch pedal, and select the appropriate gear based on the number of people pushing. Generally, the highest gear should be third, but second or first gear can be used if there are more people. Reverse gear can also be used, ensuring the car doesn't stall when the clutch pedal is released. Release the handbrake and push the car to move. Once the car is fully coasting, release the clutch (keep the foot on the pedal). At the moment the engine starts successfully, press the clutch again while pulling the handbrake, shift to neutral, and press the accelerator.
