Just curious, what are the two relays on the inside fuse panel for? Doesn't list on the little map and haven't had luck finding on Google so far.

 

The lage one is for the flashers/ turn afx av in my truck, but the Chilton book says spare and the smaller one is the horn relay according to the book. I would pull them one at a time and see what doesn't work, provided things are all working to begin with.

 

Thanks. Was recently turning off the truck and the big blue one was chattering like crazy. I'm thinking this whole truck is electrically fubared.
