    Default Question: OBC

    Just something I noticed:
    My On Board computer doesnt have any lights on the buttons , only the little screen lights up , but in the dark its hard to see the buttons !!
    Not only this , the three dials ( left/right temperature and fan speed) dont light up either .............. is this a fuse problem or did BMW just forget this?

    Default Fuse Diagram anyone?

    Do you think it could be a fuse ,
    Its very unlikely that ALL these bulbs would go out at once

    Did I mentionthat all other bulbs are ok (even the ones onthe 3 sliders for vent control work), just this section isnt working(temp dials , fan speed,OBC) dont work.

    Anyone Have a fuse diagram?

    Default 3 bulbs light the OBC. Seems like you have 2 burned out.

    Remove the OBC per Bentley and replace the bulbs.

    Went to the dealer to get the bulbs ,
    >>>Man sometimes I think , they dont know what their doing over there!!

    First they told me that the OBC takes 4 bulbs , I said that I knew it took only 3 ( from the forum) any way , i got the 4 just in case ,
    NEXT , they said the cluster panel had one bulb THAT WOULD HAVE TO BE SPECIAL ORDERED !!!!!
    I said wow , you are the only dealer in a 300 mile radius you should have all the parts , but they could only say that this is a difficult part and it would only be available in 4 days if i ordered it

    to make a long story short , after opening the cluster , turned out the OBC only took 3 bulbs .........AND THE ONES THEY GAVE ME WERENT THE RIGHT ONES , they fit inside but were a diiferent volt and ampere!!
    just for curiousity I opened up the panel and followed the instructions on Bruno's site to get to the other bulb .....
    when i saw it , i knew i could find it somewhere , so just as a long shot < I called Autozone and they had it !!!
    NOW everything looks great in the dark !!! first time for me to see colors in the dark in my beemer !!!
    I noticed another thing though , the A/M switch next to the automatic shifter doesnt light up , is it suppose to be this way or .........................????

    thanks for all your help !!
