left head light stays on

my 1991 525i bmw left head light stays on, even when I turn off the igintion.I have to pull the postive wire on the battery every time I stop my car so the battery doesn't go dead. My right head light does not work I have checked the bulb,the fuse and both are good but their is no juice going to the fuse (on the right side) HELP!!! please I don't want to send it to the shop if it something I can fix myself.
