I have a 1999 2500HD silverado 6.0L. It has factory installed fog lights they have always worked. Glue around one of the lenses failed and water entered the housing and blew the bulb. So instead of replacing I just took out the housings and zip tied the wires up. A year later I got new lens housings and put them in with new bulbs. But now the fog lights wont turn on. I have replaced the cargo/fog light switch and I have checked the fuse and relay in the fuse center on drivers side under hood. Is there a fuse somewhere else I am missing I cannot understand why these are not turning on now?
