Backup lights quit working.

So you have a multi meter to do some testing?

Yes I do.

Lets start by turning the key to the run position and see if fuse number 6 has power to both sides of ut.Thats the fuse for your back up lights.

Fuse positions not marked. ALL fuses in place on inside left firewall test as good. Positions marked with function: I E Radio, Dome, etc. NONE marked "Backup."

Theres a key to show you where the number 6 is located.

Is this fuse panel under the hood? (The panel under the dash has a completely different configuration.)

Sorry about that here is the correct one its a 30 amp circuit breaker.

The other one was for your underhood fuse box.

I found & tested all the fuses in the corresponding fuse block. All tested good. I have removed the only circuit breaker from the fuse panel, and it has continuity. What should the ohm reading be?

It should be 2 ohms or less just make sure when its installed there is power to both sides of it.

Performed all tests requested. With key on, transmission in reverse, no power to either side of fuse panel location you indicated.

So that circuit breaker doesn't have power to it on.ethier side with the key in the run position?

No. Not even w/transmission in reverse gear.

There is something VERY strange! I removed the circuit breaker from slot 6. (It's the only 1 in the fuse block.) Slot 6 is NOW EMPTY, AND YET MY BACKUP LIGHTS STARTED WORKING.

See if ethier side of the terminals where it plugs in has power?

There is now power to one side of the position, #6 (1 side only.) The backup lights work, BUT THERE IS NOTHING IN THE SLOT TO PROVIDE POWER THROUGH THE CIRCUIT. How can this be?

I had the same issue, just fixed it by checking the mini fuses under hood. I replaced the 15am ignition fuse number 11 on this diagram. My backup lights more work. Thanks
