About 2 years ago I put in the fog lights on my 05 silverado. It came without them stock and I added the stock set. They worked fine until about a month ago. When i push the switch now, the little light under the switch goes on but the fog lights themselves dont. The bulbs are good and the fuse is not blown either. Any thoughts?

TIA

Check the fog light relay. It is the one in the first row nearest the fender, and first relay from the front of the truck in the under hood fuse panel.
Maybe take a known good relay out of the horn or day time running lights. It they now work, buy a new relay.

Tried changing with the one for high beams. It didnt work. Still not working even with either relay
