PLEASE HELP!.. all lights work on my 02 focus, the dipped beam work, the full beam works but the main beam doesnt, 'one after the dipped beam switch option.. The lights stay as dipped beams.. is it a particular fuse in the engine box that could be the issue here? Ive read its number 5 in the box, if so can u buy these and replace yourself? I cant get it out, its very stuck in there.. so I cant see if its broke. Thanks in advance, Mark.
