I have a 07 Grand Prix 3800 that I'm working on a
guy before me had a problem with the fan not
turning on so he put a aftermarket temperature
controller unit on it and it stopped working I hook a
fuse to the inside fuse box on the right side of the
car and why I went back to it and I was messing
with it and now I don't have power to where fuse
go in at and now the temperature gauge is not
working also what fuse or relay would that be that I
would have to check

I'm not sure what damage has been done by all the messing around with your electrical system, but the original problem was probably a failure of the resistor that controls your fan speeds. Start by restoring your electrical system to how it was originally and then take out the resistor and change it if its fried. Hopefully no other damage has been done and it will work again.
