I have a 93 F-150 XL with a manual transmission. The reverse lights stopped working on the truck a while back and I finally got around to working on them. I figured that it was a small chance that both lights failed at the same time so I replaced the bulbs. They still don't work. I examined all the wiring around the back of the truck and it all looks good. So I got a new reverse switch that fits in the transmission. Still no lights. I checked all the fuses and they're all good. Where should I go next?

 

Probe the hot feed on the light socket for power with the tranny in reverse. If you have power I would suspect a bad ground. Follow the black wire to the very end and make sure it is properly connected to ground.

jon, it can be a bit cheaper to do some testing before buying parts!

 

some of the parts i'm not too worried about. the truck has a ton of miles on it and most of these things die (not necessarily bulbs) in the life of the truck. i also don't have all the necessary tools ready and handy though. else i probably would've done some testing.

 

dont need a lot of tools for electrical work but must have a test light to check for fire and ground. Dont just go throwing parts at it, do a little testing before hand will save you money and head aches. Power at hot to reverse lights? terminal pushouts at the connectors? Is it plugged into the tranny?
