Unfortunately, many possibilities. If you have time, start by removing both reverse lamp sockets from light assembly(and keep from touching any metal), remove bulbs from sockets, CAREFULLY INSPECT sockets and wires. New fuse of correct rating. Turn key on and try again in reverse.
Fuse still blows: Next place to look is transmission reverse electrical switch and wiring as far as you can trace looking for burned/stripped wires near transmission and wires by sockets
Fuse doesn't blow: Turn key off and install one lamp in socket at a time. DO NOT install sockets into fixture at this time. Test. Remove first lamp to check second. If still O.K., each socket back into fixture(one at a time same as before)and test. Most common problems: Sockets contaminated, wires shorting at sockets, bulbs installed incorrectly shorting to ground.

This could be caused by the transmission range selector switch on the tranny, no sure how without the wiring diagram, but seems to ring a bell from my 20 years at a ford delaer.
SOURCE: Hi, everytime I put my tracker in reverse I blow
It seems that the reverse light is shorting with the blinker. And that is why the reverse lights do not function. Please check it out and insulate the wire where it is shorting . Your fuse will automatically stop blowing.

Hello and welcome to FixYa....Sounds like you have a direct short in the NSS, (neutral safey switch) RLS (reverse light switch)--- if it's fuse # 11 that you are blowing, then it's the safety switch.
It's located on the transmission, passengers side, about half of the way up. It is a fan shaped switch with a big nut at the bottom, it is adjustable.
It has slider type contacts in it that slide and click into position to complete a circuit when the gear selector is moved. Depending on type of tranny, the switch serves as 2 purposes, neutral switch & backup lights. It's probably full of gunk. I have removed them, taken them apart by removing the phillips head screws, cleaned with electric contact cleaner, coated with dielectric grease, reinstalled & and got another year and a half of service.
Here is what the switch looks like....I hope this helps, good luck with your Jeep.

SOURCE: where is the reverse light
The backup lamp switch for your Sorento is located on top of the transaxle.
I hope this helps.
