Solution

1. Preparation

Gather necessary tools and parts.

2. Inspect Door Switches

Tools Required: Multimeter
Check each door switch using a multimeter:
1. Remove the door panel to access the door switch.
2. Disconnect the switch connector.
3. Measure continuity across the switch terminals when the switch is activated.
4. Replace any faulty switches.

3. Examine Wiring

Tools Required: Wire strippers, electrical tape
Inspect the wiring harness:
1. Look for frayed, broken, or pinched wires, especially at the door hinge.
2. Repair any damaged wires by stripping and splicing them, then secure with electrical tape.

4. Test Interior Light Switch

Tools Required: None
Check the functionality of the interior light switch:
1. Locate the switch, usually found on the overhead console.
2. Toggle the switch to the "off" position to see if the light turns off.
