Assuming you have replaced the bulbs with no joy and the fuses are good, your problem may be linked to the Neutral Start Switch on the side of the transmission. This switches on that circuit when the transmission in in reverse. Many times the contacts inside it become worn or dirty. It can be disassembled cleaned and re lubed or simply replaced. Hope this helps.
I would check the wires just behind the light. I had the same problem and the wires were broken a little just wiggle them as the lights are on.
intermitten problems are the worst to figure out i would first start by changing the bulbs then i would change the wiring harness. i know i had a car that when the tail lights were on the blinkers wouldn't work and it turned out to be a short in the harness.
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.
No.No.
Yes. They work fine if the lights are off (ie. during the daytime) but when the lights are on all the brake lights are off. Our Grand Cherokee has tons of problems. The ac sometimes does not work, the gauges go crazy, the power windows play dead sometimes. We got it checked out. Mechanic says our body control module is going bad.
The switch that turns on the backing lights also ensures that the vehicle can only be started in "Park" or "Neutral". It is located on the transmission housing. In many cases the switch can be removed, the contacts cleaned and the part replaced.

Replace the neutral safety switch on the trans, it also triggers the backup lights. You can try to remove, clean and adjust it first, it worked for me. It is located on the passengers side of the auto trans.
if it is a jeep Cherokee it needs a neutral safety switch mounted on the passenger side of the transmission. if it is a jeep grand Cherokee it needs the backup switch located on the drvers side of the transmission
The fuse for the overdrive trans and backup lamps is a 10 amp fuse located in position number 27. If it is blown you will also have no backup lights.

how do you replace backup lights on 99 grand am?
Where it is exactly I do not know suffice it to say that it is somewhere on the transmission.

Yes
It doesn't have any. The only C2 (1963-1967) with backup lights is the '67.
