my Toyota Corolla E140 (2006-2013) dashboard lights are not working what to do

Solution

1. Preparation

• Tools Required: Screwdriver set, multimeter, replacement bulbs, fuse puller.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect the Dimmer Switch

• Locate the dashboard dimmer switch, usually found on the headlight control stalk or on the dashboard.
• Turn the dimmer switch back and forth to check for functionality.
• If faulty, replace the dimmer switch as per the manufacturer's specifications.

3. Check Fuses

• Open the fuse box cover, typically located under the dashboard or in the engine compartment.
• Identify the fuse associated with the dashboard lights (refer to the fuse diagram).
• Remove the fuse using a fuse puller and inspect it for damage.
• Replace with an identical fuse rated for the same amperage if blown.

4. Test Dashboard Light Bulbs

• Remove the dashboard cover using a screwdriver to access the instrument cluster.
• Carefully remove the bulbs from their sockets.
• Use a multimeter to check for continuity or replace any burnt-out bulbs with new ones.

5. Inspect Wiring Harness

• Check the wiring harness connecting to the dashboard for any visible damage or corrosion.
• If damage is found, repair the wiring or replace the harness as necessary.
• Reconnect all connectors securely before reassembling the dashboard.

6. Reassemble and Test

• Reassemble the dashboard cover and secure it with screws.
• Reconnect the vehicle battery and test the dashboard lights.
