I have a toggle switch that controls my fog lights and I've checked ever ground, power, fuse, relay, etc. Well ever once in a while they won't work with when I use the switch but a couple days later they will. Has anyone ever run into this problem that possibly give me some kind of insight ?

 

Please excuse my improper typing ^^^^, I have one of those 3 prong light up toggles so either i have a loose wire or the switch might be faulty but It's getting more frequent and ticking me off
