Hi, I bought my 2003 Lariat used about 8 yrs ago and no major issues(knock on wood) Then 2 days ago I lost use of my interior lights, and power windows. I know to check the fuses but when I went on line to check where they were it said there were 3 fuse boxes, I have only found 2! how do you check the relays? Please help!

 

Come on! Really? No one has any suggestions? This is a first! Ask a man about a vehicle, a truck no less and they have nothing to say!
