Solution

1. Preparation

Tools Required:
- Socket set
- Screwdriver set
- Multimeter
Disconnect the negative battery terminal to prevent electrical shorts.

2. Inspect and Replace Bulbs

Remove the lens covers for the turn signals using the screwdriver.
Check each bulb visually for any signs of blackening or broken filaments.
If a bulb is burnt out, replace it with a new bulb of the same specification (e.g., 12V, 21W for turn signals).
Reassemble the lens covers securely.

3. Check and Replace Turn Signal Relay

Locate the turn signal relay in the fuse box (refer to the vehicle's manual for exact location).
Remove the relay by pulling it straight out.
Test the relay with a multimeter for continuity.
If defective, replace it with a new relay of the same type (usually marked in the fuse box).
Reinstall the relay into the fuse box.

4. Inspect Wiring and Ground Connections

Examine the wiring harness connected to the turn signal assembly for any signs of wear or damage.
Use the multimeter to check for continuity in the wiring.
Ensure that the ground connections are clean and secure; tighten or clean as necessary.

5. Reconnect Battery and Test

Reconnect the negative battery terminal.
Test the turn signals and hazard lights to ensure proper operation.
