The cigar lighter in my W203 saloon does not light up at night,also the cigar lighter does not latch but there is power to the socket as I can use a charger. Although I do not smoke I do like things to work properly, especially to illuminate where they should so how do I remove the assembly to change the bulb or replace it? Also, the part where you push in a pen or screwdriver to operate the emergency Park release is exposed, it looks like there is a sliding cover but if so I cannot move it to the closed position, is there a cover? If so I will try silicon spray and see it it moves. Thanks.
