When you open the door your interior lights come on.If the truck is not running and the door is open the lights are suppose to turn off after 20 minutes.

Found that it's called, Battery Rundown protection

What do you replace to fix that?

Mine act as if they're trying to turn off but they go dim and I hear a muffled buzzing.After I tap on the switch on the side where the door makes contact to turn it off it will light back up.

Sorry for all the questions.Thanks in advance
