fuses

First off, I am not a mechanic, but fairly competent working on a vehicle - if I know what is wrong!!
Recently, both of my fog lights quit working. Checking the under- hood fuse box, the spade fuse for them is fine. Now, the question, there is a second 'fuse'? labeled fog lights - or is it a relay??
In the picture it is the teal/aqua colored rectangular piece in the bottom row at the left end.
How do I check this whatever it is (fuse/relay/??) to see if it is OK??
Are there anymore fuses for the fog lights located in the interior fuse box??

Thanks, Pops

 

yes, the teal boxes are relays. but relays generally don't fail. keep your hood and fuse box cover open, key the truck on, and flick the fog lights on/off. if you can hear it clicking, 75% of the time, the relay is good.

but have you checked bulbs yet?

 

if the fuse is good, check the green wire on the fog lights connector for power with the fog lights on.

 

Will try these options either later today (gotta go help my father-in-law around his house shortly) or tomorrow.

THANKS, GUYS!!!!!
