electrical problems

[figment]

Has anyone had a problem with the fuse box under the hood? I have, when my Tahoe is running and i wiggle the fuses just enough to get the slightest movement, it'll shut off.

I pulled the fuses and cleaned up the contact points, some tarnishing, both on the fuses themselves and the clips with an emery board, to no avail still shuts off. any suggestions?

I found this out after it shut off on my wife in the middle of an intersection, and after a little poking around .

Is there a contact point on the back side of the box that comes loose?, or am I going to have to replace the the fuse box?

On my burb there are a few different cables/wires that screw into the back facing the firewall. There are also ground wires connected. I would tighten wires going to the box and find the ground and clean and retighten.

I think there are 2 ECM fuses there, I would look closely at them, cause if the ECM loses power it would probably shut things down.
