1992 300SL #5 fuse burnout problem
 

1992 300SL my #5 fuse keeps burning out, replaced brake switch which was told would be the culprit but no go. Any more ideas out there? thx rick

does it go out only when appling the brakes? have you replaced any bulbs recently? that fuse encompasses many other functions besides the stop lamp switch. start disconnecting one at a time the other items on the #5 fuse list.
