Solution

1. Preparation

Tools Required:

Disconnect the negative battery terminal to prevent electrical shorts during repairs.

2. Inspect and Adjust Dome Light Switch

Check the dome light switch position; it should be set to "door."
If faulty, replace the dome light switch:
- Use a screwdriver to remove the light assembly from the ceiling.
- Disconnect the electrical connector.
- Replace the switch and reassemble the light assembly.

3. Inspect Door Latches

Open each door and inspect the latch mechanism for any obstructions or damage.
Lubricate the latch with penetrating oil if it appears to be sticking.
If the latch is damaged, replace it:
- Remove the door panel using a screwdriver and trim tools.
- Disconnect the wiring harness and remove the latch assembly.
- Install the new latch and reassemble the door panel.

4. Check Wiring and Connectors

Inspect the wiring harness leading to the dome light and door switches for any signs of wear, damage, or corrosion.
Repair any damaged wires or connections as necessary.
Ensure all connectors are securely fastened.

5. Verify Bulb Functionality

If the bulb is found to be faulty, replace it:
- Remove the bulb from the light fixture.
- Test the new bulb with a multimeter before installation.
- Install the new bulb securely back into the fixture.
