Hi, new to forum, but love cars. Need help in sending me in the right direction in finding a problem with my 2004 trailblazer. Just lost all dash lights, speedo etc. It tried to come on and and went off right away. As I am handicapped, I need help in finding my way quickley and easeily. I don't know where a relay may be, or a fuse block that hase the fuse. Well you can see my prdickerment. Tks in advance. Paul

There is fuse box under the hood and one under the second row seat if i remember right.

Tks, I'll check in th AM. Again tks. Paul

Guess What? Next moring all was well??? Is there some way to find out what happened? Maybe a scan, or something simpler? Paul
