Okay, I'm stumped on this one. I bought a 2013 Silverado in January and the truck has ran great until the last two weeks. Symptoms are sputtering when accelerating and uphill, reduced fuel mileage, and general sluggishness. I started with the most simple (injector cleaner, higher grade gas, etc.).
Now before taking it into the dealer (out of warranty by a month and a 1,000 miles), I went to check the fuse and relay to make sure there wasn't any obvious issues with those. After opening up the box and looking at the diagram, I was surprised to not find either a relay or a fuse where the diagram said they should be. Pics below.
I'm super confused. Is there a reason why the relay and fuses are not located where they should be? Am I missing something? Thanks in advance for any help.
