i have had the "right turn lamp" warning or whatever too, got out and checked it and it was fine and then the warning went away a little later.
Check the alternator + terminal make sure its tight. then make sure those battery terminals are extra tight , maybe even get a terminal cleaner and use it on that.

Did you ever find any mice nests in your car anywhere? Sounds like a bad dash connection somewhere. I would guess a ground wire for either the entire underdash wire harness or just a cluster ground wire. Sometimes these are impossible to find. It would really help if someone could post up a ground point schematic for an LS

Check the ground wire where it connects to the body.

Check the ground wire where it connects to the body.

you mean the ground wire that is comming off the battery to the inside of the trunk.........i have checked that and cleaned it ....and even went as far as cleaning the battery posts on the new battery and the clamps......the problem is still there

Dash failures

Sounds like a bad ground under the dash. Good Luck because anything in the dash sucks to work on !!
