Hey everyone. My cousin owns a 2004 Pathfinder Armada. Recently he has been having trouble starting up his car. He changed the battery, got it tested, tested the starter, and even replaced the terminals. When we were at Napa, the counter guy told us to check the starter relay. We popped the fuse boxes in the bay and looked for the starter relay, but couldn't find anything. Anyone want to point me in the right direction, so I can test it with a multimeter? I've tried searching the FSM, but couldn't really find anything.

Any help will be appreciated!
