if you changed the bulbs and still nothing.. its the reverse switch that's on the tranny. about a 10$ fix and 5 min to replace. good luck!
what to do if my reverse lights on my 1993 gmc 1500 truck wont work
check the wiring. its probably shot
Most likely the reverse lights were attached to the light bar.
the reverse light switch is either out of adjustment. or broken. new one should be fairly cheap
First check the fuse, then check the bulbs, then check the switch.
It can be your switch or the fuse try checking the fuse first.
In those tail lights there is a circuit board. If it goes bad it will cause all kinds of problems.
It could be a short in the wiring, or a fuse or the headlights themselves might be bad. I hope this helps
Defective reverse light switch.
If the reverse lights are not working on a 1999 Chevy Suburban, be sure to check the fuse panel. If all the fuses are in working order, check the wires for any loose connections. Faulty wires can result in little or no light input.
Check your fuses
