What would cause the fuse for the brake lights to blow every time you put the car in drive?

Check the circuitry to the backup lights. The same fused circuit is probably used for both brake lights and backup lights. As you go past Reverse, the backup light probably is turned on briefly, causing the fuse to blow. It's just a thought, but I'd think it worth checking.

I'm not sure I understand your question. I can't tell if you have one or two different fuses "blowing." The only thing which causes fuses to "blow" is a short circuit condition in the circuit which the fuse protects. IF you have two different circuits blowing fuses, then you have at least two short circuit faults. j3h
