What could be the problem with the back up lights on my 2003 Chevrolet S-10?

Question

For some reason they don't work. I changed both of the bulbs and they still don't work. Could it maybe be a fuse? If so what fuse?

Answer 1

If the fuse is still good it may be the wire on the transmission has come off or has been pulled apart by a stick if you have been going thru some brush. Usually there is a wire on the transmission when you put it into reverse a switch is activated to turn the back up lights on. Some times the switch is in the shifter linkage.

Answer 2

There are 2 fuses. (both in the underhood fuse box)

Fuse #1   B/U LP 25amp

        #2    VEH B/U  15amp.

If fuses are good, check wiring at connectors to( park neutral position switch) at side of transmission. (known problem area, connectors bond to switch).
