I circled empty spaces in the cargo area fuse box and the under hood fuse box on my 2007 GL450. Am I missing relays? I see lots of fuse diagrams but NOTHING on the relay layout and part numbers. Please help! I know that some components on my trunk aren't functioning, so I want to rule out the simple things like fuses and relays especially missing ones.

The paper fuse diagram that came with the truck, if I remember correctly, has the relays listed on it. If it's not in your owner's manual book, I've heard that some have found it in the spare tire area - maybe in the middle of the spare or something like that?

I have that, and it doesn't say WORD ONE about relays. Zero. I was shocked. OTher ideas?

Hmmm. I could've sworn that my paper had relays listed on it. Maybe it was a different paper? Maybe I ended up finding something online somewhere and printed it out? Or maybe I'm just not remembering correctly! I don't have the truck right now, but can check when I get it back.

You know... now that I think about it more, I think I did find the info online somewhere and then WROTE it into those blank boxes.

For reference: pics from 2007 GL450:

First two are engine fuse box, last is trunk fuse box
