Okay this happens all the time with any of the doors open. Lets say somebody is getting out of the car. They open up the door and the chime thing goes off. Well when it goes off sometimes it will short for a second and the lights will flicker off for like .3 seconds and the radio will turn off and back on. It only does it when the doors are open. And when it does it i can hear a click noise. is that black module that does the chime going bad?
