Hi and welcome to solve the problem behind cd /radio won't turn off automaticaly when opening the door and the key is out of ignition
this is due to bad oxidation in switch contact in the door panal so let's solve the problem
first remove the door switch


i think the bolt is star type


then remove the connector switch


now you have the switch first remove the rubber cover


use - screw driver just remove the cover don't be hard these plastic cover are very easy to brake



the cover removed remove the metal bar next


now remove the button as you did in the cover


chick out for oxidation and use oxidation remover spray but dont forget the inside two metal


too much oxidation here



install back the button first then the metal




last thing re install the rubber cover and screw the bolt chick out if the key in ignition u must hear ding sound once the key removed CD player will turn off and the dome will light any time you open a door
thanks and regards sorry if u found grammatical mistakes i am not native speaker
