"There are 2 red, 2 white and 1 blue from the ceiling. From the fixture there are 2 white and 2 black. Any info is appreciated."
I am guessing that the house uses conduit to cary the wiring.
You need to also open up the switch and indicate what wires are in there. Which connect to the switch. And if there are more than one conduit what wires are in each conduit.
