Fuse problems

[earlalderfer]

I have 1986 BMW 535i

Fuse #12 keeps blowing, all other fuses are good

Active Check, Brake lights, radio, on board computer, cruise control and speedometer does not work.

Tach, turn signals, ligths, gas & temp gauges work

Any ideas?

id ck water in rear lights (bad seals) can fill up w/ rain

If it is not the brake lights, try disconnecting the antenna and see if it still is blowing fuses. Go down the list of things that don't work, disconnect one at a time, and see which circuit is the culprit..
