Fuse block loses power
So on my 3.1 v6 the fuse block loses power if I hit a bump or move it. My stereo goes out and then comes back on. Sometimes I have to move the block around to get the stereo to turn back on.. which wire would I need to check ? Also my windshield wipers move like a half cm. Any help

Re: Fuse block loses power
The 'RADIO" fuse maybe ?!?! 
It's possible the tabs that hold the fuse in place are bent / warped and not allowing firm contact with fuse at all times. If that's NOT the case then your going to have to un-screw the fuse block and flip it over to get a good look at all of the wires leading to and from the back of it. Not really an "easy" thing to do because of it's location,... but no other way to know if the wiring and terminals are OK without looking at it to be sure.
Most of the incoming power wires will be heavy gauge wire (usually RED PINK OR YELLOW wires ) and most of the out-going wiring will be smaller gauge wires ( MANY different colors, but pink or red ! ) I'd focus on the incoming wires first. Some incoming wires feed a single fuse while other incoming wires feed power to 2 or 3 fuses. It's very possible that one of these incoming power wires is "fried" and is causing a bad connection to 1 or more fuses as a result.
It could very well be the outgoing "RADIO" fuse wire that got a little "burnt" too,.........
Good luck !
