535i electrical problem

[sweetrayray]

I am having some electrical problems. My driver's side tailight and parking/turn lights are not working. I disconnected the battery and let it stay unconnected for over an hour and when I reconnected the battery the lights worked for a little while and stopped working again.
Is there something wrong with my LKM Module or is it my fusible link.

Please help.

Rayray, the first thing to do is play with the bulbs. My car's a 1985 535i, and it has these funky bulbs that don't have any wires going to them...they just twist into a mounting spot, and the juice flows to the mount. After a while, these mounting contact points get a little grunge on them, and then the bulbs don't fire.
BMWs seem to have electrical storms when one thing goes out, and some other things quit working as a show of sympathy.
Pull back the molded plastic cover in your trunk, and twist those bulbs out, then twist 'em back in.
Then tell me what happens!
