LKM Light Control Module

I recently got a new LKM Light Control Module for my E34 5 series because my left side tailight and parking light where not working after checking the bulbs. The parking light wouldn't work but when I turned on the blinker the parkinglight/blinker would work, same for the rear tailight. SO when I put the new LKM in the fuse box it din't change a thing. Would there be something else that would be wrong? My blower motor doesn't work also, and the fuse for the horn keeps blowing out.

Please Help, very frustrated.

mmmm check wires that run along the trunk hinges some times they get pinched I had same problem

I believed the new LKM needs to be programmed by the dealer.
