Yes that is the thing to do. If you go into it that a new one will solve the problem, it could also fail and lead you to think it can't be the fuse box and go in the wrong direction. If you swap in a repaired one, you know it is taken care of and done. I did this with one. I sent it to Dragon2U and it's waiting on me to put it in the truck now. Once I swap that one out I will send the one I take out to be repaired and then swap it into my other 05.If I locate a new "GM Fuse & Relay Box 10375734" part/module, should I have this repaired also? I'm thinking of a complete switch-out of parts, which will have less downtime.
