1. Starter Motor Issues:
- The clicking sound could indicate a problem with the starter motor. It may not be receiving enough power to engage properly, or the solenoid that activates the starter may be defective.
2. Loose or Corroded Battery Connections:
- Even though you have replaced the battery, ensure the battery terminals are clean and free of corrosion. Loose connections can cause electrical issues, including clicking sounds and malfunctioning warning lights.
3. Faulty Ignition Switch:
- A worn or defective ignition switch can cause intermittent electrical problems, such as clicking sounds and flickering warning lights.
4. Bad Ground Connections:
- Poor grounding can cause various electrical problems, including clicking noises and warning light issues. Check the ground connections to the battery and chassis.
5. Transmission Issues:
- In rare cases, a clicking sound under the drivetrain can be related to transmission problems, such as low transmission fluid or worn-out components.
6. Faulty Wiring or Relays:
- A short circuit, damaged wiring, or faulty relays in the electrical system can also lead to clicking noises and warning light flutter.
7. Faulty PCM:
- The Powertrain Control Module (PCM) controls various systems in the vehicle, including the starter and ignition. If the PCM is faulty, it could cause the clicking sound and warning light flutter.
Diagnosing the exact cause of the clicking sound and warning light flutter requires further inspection and testing. It's recommended to have the vehicle inspected by a qualified mechanic who can accurately diagnose and rectify the issue.
