check the fuses in the fuse box and see if there is any burnt ones. Good luck

It may not be a fuse at all it sounds from the description (14a) it is a 14 gauge fusible link which is a wire that will burn out like a fuse, check for 12 volts with a multimeter or test light from the fuse box and then continue down the circuit until you cannot find power. Just before this point you should be able to see a part of the wire that looks different and that should be the fusible link.

the backup lights and cigar lighter are located in under hood fuse box on drivers side of vehicle. both are mini fuses.the fuses have a number diagram to find them. backup lights are #42 and cigar lighter is #34

Fuse 14 10A* Back-up lamps
this is from the owners manual, doubth this is the problem, if fuse is good the range selector switch (which contains the reverse light switch) on the side of trans may be bad

If you backup lights are not working as well, I would say check the fuse for the backup lights, if the fuse is good, see if you are getting power to that fuse. We had this problem and after weeks of searching and changing sensors, we found the backup light fuse was good, but not getting power. Ran a wire from that fuse to the cig. lighter fuse and all woprksf great.

No, but there is a backup light switch, it will be under dash on steering colume,

Now you should take it to an Authorized Service Station.

the backup lights are a part of the hazord lights if your hazord lights work its the reverse neutral switch thats at fault
