Back-up lights don't work

[stuball]

The back-up lights aren't working on my '08 Tundra. I looked for the B/U fuse in the fuse box in the engine compartment and couldn't find it.

Does anyone know which fuse would be for the B/U lights? Or could it be some other problem than the fuse?

Thanks.

I did find the B/U light fuse on the fuse panel under the dash. It certainly is inconvenient to access. Anyway, it was a blown fuse.

Thanks for the info...at least now we know where to look.

Did you have anything plugged into the trailer plug that might have blown the fuse? Are you running stock backup bulbs?

Yes, I'm running stock B/U bulbs.

However, I did hookup and plug into a neighbor's travel trailer to my trailer plug in order to see if my stock rear view mirrors might be sufficient to see behind me without having to use clip-on mirrors. After that episode my back-up lights no longer worked.

After talking to a couple of neighbors, that IMO, are certainly more experienced with auto mechanics than I, they thought replacing the present 10 amp fuse for the B/U light with a 15 amp was OK considering that I will be using it in the near future on my trailer that has B/U lights.

Do you think using a 15 amp to replace a 10 amp in this situation is OK?

My last truck was a '04 GMC that had pulled this same trailer of mine and the GM dealership suggested at the time replacing a burnt out trailer braking fuse (not B/U light fuse) with one that was 5 amps higher would be safe to do so. I don't know. I'm asking is this OK?

I say no never increase the fuse size unless your in a serious emergency pinch only. Sounds to me the trailer you hooked up to probably had a short in the backup circuit and it caused you to blow your fuse, so the fuse did what its suppose to do. If you increase the fuse size you may end up causing some wires to burn before the fuse blows and could cause a truck fire.
