hi all . I just wanted some input on a small issue I have. I have a 98 d1 that the interior lights work sometimes or just turn on and off themselves . ( they always work when switched on manually ) along with that there is no door beeper if the running lights are on, the rear window defroster doesn't work unless the interior lights are functioning, as well as the rear fogs, the wiper intermit doesn't function and a few more things. am I wrong thinking its the multi function unit ?
