- Gently tug on wires to check for loose connections or breaks.
Tools Required: Screwdrivers, trim removal tools.

3. Test and Repair Short Circuits

Sub-steps:
- Connect the multimeter to the circuit where the short is suspected.
- Set the multimeter to continuity mode and check the circuit.
- If a short is found, trace the wiring back to locate the source of the short.
- Repair or replace any damaged wiring or connectors as necessary.
Tools Required: Multimeter, wire strippers, electrical tape, soldering iron (if needed).

4. Replace Blown Fuses

Sub-steps:
- Locate the fuse box and remove any blown fuses.
- Replace with new fuses of the same amperage rating.
- Recheck the circuits to ensure proper functionality.
Tools Required: Fuse puller or pliers.

5. Reassemble and Test

Sub-steps:
