Weird fog light issue

[68whiskey]

Hey guys. When got my 4Runner, the fogs did not work. I swapped out the relay, and they worked for a few days. Now they aren't working again. Does anyone know or have an educated guess as to why they would be popping the relay? Intermittent problems are terrible, and the fact that its electrical makes it even worse. Everything else operates as it should, so I don't even know where to begin. Any input would be greatly appreciate. Thanks!

Factory fogs or aftermarket? Are you sure it's the relay again and not something else?

Here is a video on a normal 5 post automotive relay that helped me at least understand how they work. Also I would put an inline fuse before the relay if there is not one already.

Thank you for the video. Like you, this helped me to understand them at the very least, and a fuse is not a bad idea.
