99 Lumina Break Issues

Some conflict with the bottom brakes no working. Seems to work when the TURN SIGNAL FUSE is pulled out.. Is there a short going on? Is the fuse box malfunctioning? HELP ANYONE

imho, it's the turn switch. The upper brake light is wired directly to the brake switch. The lower ones go through the turn switch because the same bulbs are used both for brakes and for turns and one has to cope with it somehow when the car brakes and turns simultaneously. Does it help if you move the turn switch rod up-down-left-right-forward-brackwards a little? If it does then the turn switch definitely needs replacement ($60 plus one has to borrow two pullers, one for the wheel, one for the wheel plate or how is it called)

i just had this repair on my '93. all works fine except yesterday i noticed that my signal is not canceling after my turn is made. just a fluke or maybe an installation problem.
