my Toyota RAV4 won't start and just clicks, what should I check?

Solution

1. Battery Inspection and Replacement

• Sub-steps:
  1. Disconnect the negative (-) terminal first, followed by the positive (+) terminal.
  2. Clean any corrosion from the terminals using a wire brush.
  3. Reconnect the terminals securely and re-test the vehicle.
  4. If the battery is weak (below 12.4 volts), replace it with a new one of the same specifications (usually a Group 24F or equivalent).

2. Starter Replacement

• Sub-steps:
  1. Disconnect the negative (-) battery terminal.
  2. Remove any components obstructing access to the starter (e.g., air intake duct).
  3. Locate the starter motor; it is typically mounted on the engine block near the transmission.
  4. Unbolt the starter using the appropriate socket (usually 10-15 mm).
  5. Disconnect the wiring harness from the starter and remove the starter from the engine bay.
  6. Install the new starter by reversing the removal steps and torque the bolts to the manufacturer's specification (typically around 20-30 ft-lbs).

3. Relay and Fuse Checks

• Sub-steps:
  1. Identify the starter relay in the fuse box (consult the owner's manual for location).
  2. Swap the relay with another identical relay to see if the issue resolves.
  3. If replacing the relay, ensure the new relay is compatible with the RAV4 specifications.
