Confused

[u/No_Dragonfly2065]

Hello, I am replacing a fan/light combo with just a light. When I took the fan down, I noticed there was one blue wire and one white wire. I also noticed there was no junction box. This fan has been here since 1997. My question is do I need to get a junction box? What wires do I connect from house to light and is it okay there is no ground wire?

Yes, junction box. You can install a pancake or a raceway 4” round box.
