fuse #9 problem with 1990 230E W124
 

Hi I am not very experienced with fuses - but my fuse number 9 failed - so i dediced to replace it - it is white fuse 8 amps - The card that comes with the with the fuse box describes fuse no 9 as " diagnostic term. 6, hazard warning system, clock , front roof light (electronic radio, vanity mirror light, relay comfort circutry term. 86) -"

The problem is when i replace the fuse with onother white fuse - the interior of the car lights up like a christmas tree & there is no way of shutting it off. Can any one help?

Thanks
