My Jeep starts and runs fine going forward. When I put the transmission into reverse I blow the one fuse for the turn lights, back up lights etc. It drives forward and no fuse blows. I took out the bulbs to see if a bad bulb but it still blows the fuse when I shift into reverse. What can I do?

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.
