Is there a fuse for the backup lights?

Hi Aaron, there is a fuse in the backup lights circuit, however its not solely for the backup lights. Its fuse 20 on the junction block. But its also feeding the combination flasher and AZC, so probably is ok, at least you didn´t report any problems with that.

What to do if there is no backup light?

With the gear selector lever in any position other than Reverse, there should be no continuity. If the switch fails either of these two continuity tests, replace the inoperative backup lamp switch. helpful? Its mounted on the valve body.

What happens to the back up light switch?

The backup lamp switch cannot be adjusted or repaired and, if inoperative or damaged, the entire switch unit must be replaced. The backup lamp switch controls the flow of battery voltage to the backup lamp bulbs through an output on the backup lamp feed circuit.

If the fuse is blown, replace it; check the reverse lights and if it blows again, you’ll need to start tracing the wires because there’s a short somewhere down the line. Figure 3.

I checked fuse #15 in the passenger floor board and its good. I also checked w/ a test light and have no power to the lights or bulbs. Both bulbs and LEDs are good. Any ideas? I cant think of anything else. Thanks! I know this sounds crazy. But flip the bulb socket around.

Why are my backup lights not working on my Jeep?

How to check if a fuse is OK?

Start at the CU by checking all terminations then with a voltage indicator start at the fuse/MCB and check at all fittings on the affected circuit. MCB or previously loose connection somewhere between MCB and failed lamp now open circuit. if MCB is ok check continuity of L-L, N-N and E-E between CU and light fittings

What to do when Your Backup lights are not working?

When the two wires are bridged together with the key on the reverse lights should work if the switch itself is defective.

Is there a fuse under the hood for the reverse lights?

This is what I’ve found while trying to troubleshoot this problem, maybe someone can help me. 1) The fuse under the hood for the reverse lights is good and had power across it while the gear select lever is in Park and Reverse, but no other gears. 2) I do hear a relay snapping on/off in the dash somewhere when I remove and reinstall the fuse.
