Solution

1. Preparation

Gather tools: Flathead screwdriver, multimeter, and a cleaning cloth.
Ensure the vehicle is in 'Park' mode and turn off the ignition.
Disconnect the negative terminal of the battery to prevent electrical shorts.

2. Inspect Door and Trunk Switches

Sub-step 1: Locate the door and trunk switches mounted in the door frame and trunk latch.
Sub-step 2: Use a multimeter to check for continuity in each switch. A lack of continuity indicates a faulty switch.
Sub-step 3: If a switch is found faulty, proceed to replace it.

Sub-step 1: Remove the panel covering the door switch (if necessary) using a flathead screwdriver.
Sub-step 2: Disconnect the wiring harness from the faulty switch, then remove the switch from its housing.
Sub-step 3: Install the new switch by reversing the removal process and reconnect the wiring harness.
Sub-step 4: Repeat for any additional faulty switches.

4. Reconnect Battery and Test

Sub-step 1: Reconnect the negative terminal of the battery and ensure it is tight.
Sub-step 2: Turn on the vehicle and test the interior lights and functionality of all switches.
Sub-step 3: Monitor the interior lights to confirm they turn off automatically after exiting.
