I have been chaning my interior lights over to led ones all the map lights work and the door and center console lights were fine at first, as i finished off by doing the rear pillar lights the whole circut now does not work. the map lights and glove box lights are fine. i have tried swapping the polarity of the bulbs around, but no joy, is there a seperate fuse? i checked the two interior ligh ones, for some reason my alarm went off when i took one of them out. any help would be great. the fuses are ok. when i got in teh car tonight they worked for a few seconds then cut out again??? how much would bmw charge to look at it?
