HI all just a quicky for the gurus out here.
my sierra has no reverse lights, went out and tested the wiring and there is no power going to it at all, Is there a switch or relay that fail on the sierras? i cant be botherd to do out in the rain and crawl around in the mud to find it (unsealed driveway

) so im asking a nice stupid question on here.
if there is where is it?
