Hi. Please help. While re-installing the rear interior plastic panel, I noticed my dome light shut off. Non plussed, I finished the task and moved on.

Question edited for clarity and add maker.

its either a bad door switch,or could be the dome override switch by headlight switch,or your interior light switch is all the way up

Time delay relay is the relay that allows the interior dome light to remain on for a brief time when you enter or leave the car.Usually the lights will remain on for a few minutes and then dim down and finally off.

It sounds like the daytime running lights were put on that circuit and the relay removed to keep them on constantly.
This sounds like a time and material repair that a shop will have to do. Tracing the wiring installed by the previous owner may be required to find out what was done.

Do you has an after market (non-factory) alarm system?
==
Locate and check the alarm module's inline fuse(s) and relay(s)
Open covers and check every dome light bulbs.
Clean the door and rear hatch electrical contacts.
Some interior lighting system has a "slow dim" or "theater" lighting module. Check for loose connection at the module.

First thing to check is the interior light / dome light control. It is usually located to the left of your instrument panel (where your odometer is located). It you move this dial up or down it will control the intensity of interior lighting.

However, if that does not cure the issue, it is possible that you have a short somewhere, or a bad bulb for the instrument panel. At that point, I'd take it to your local repair facility and have them check it out. Changing interior lighting or testing for electrical failures can be a difficult task.

Interior Lights Circuit Description
By using a feature called inadvertent power control, the body control module (BCM) supplies power to all of the following components:
• The courtesy lamps
• The dome lamps
• The rear view mirror reading lamps
• The instrument panel compartment lamp
• The rear compartment lamp
The left front door ajar switch turns the interior lamps on through the BCM by grounding CKT 394. When the left front door is open, the switch is closed. This condition provides a ground and a door open input to the BCM. The BCM then grounds the following lamps through CKT 156 in order to turn the lamps on:
• The courtesy lamps
• The dome lamp
• The rearview mirror lamps
The right front door ajar switch and the rear door ajar switches turn the interior lamps on by grounding CKT 395 from the BCM.
When the ignition key is removed from the lock cylinder, the interior lamps remain on for approximately 40 seconds.
The BCM provides an interior lamps-on delay after a door is opened. The lamps remain on for approximately 40 seconds or until the ignition switch is turned to the ON position. The 40 second lamps-on delay reduces to 4 seconds if a door is opened within 2 minutes of the ignition switch being moved from the ON position. The interior lamps immediately turn off when the vehicle begins to move.
The dome lamp OFF-DOOR-ON switch controls the dome lamp. When the switch is in the OFF position, the dome lamp remains off. When the switch is in the DOOR position, the dome lamp lights when a door is opened by the BCM grounding CKT 156. When the switch is in the ON position, ground is supplied through CKT 750. The rear view mirror reading lamps are controlled by the rear view mirror reading lamps switch or through CKT 156 from the BCM.
Voltage is supplied at all times to the BCM through the INT LPS fuse. The BCM supplies voltage to the interior lamps through CKT 1732.

Battery Run Down Protection
When the ignition switch is in the OFF position, the BCM turns off the power to all of the interior lamps after 18-22 minutes.
The BCM will reset the inadvertent power control relay output when one of the following actions is performed:
• Open or close a door.
• Turn the ignition switch to the ON position.
• Turn off any interior lamps that may be on.
• Press the power door lock switch/keyfob button.
• Press the decklid release keyfob button.
