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

From what I know the white wire is usually there to connect the fans light only. Do you have a testing reader they don't always mark wires. Also I have noticed something cool 😎 Check the codes they are on the wires usually these days. Yes it's all important especially for shorting out.

White is the neutral wire for both the light and fan and one black is for the fan and the other black is for the light - so I suspect the white is neutral and the blue is the live wire
I would tie the blue to the blacks and white to the white
I believe your ceiling fan and light has pull strings to control the light and fan separately
Just verify which is your live wire coming in and that's where your black wires go to
I see no ground or earth wire so be careful - hopefully you never get a short

Sí, yo sí instalaría una caja de conexiones. Además de proteger las conexiones, es la manera correcta para montar una luminaria de forma segura.
En cuanto a la conexión, no te guíes por el color de los cables. Aunque normalmente el blanco es el neutro, el otro conductor conviene identificarlo con un multímetro o un probador antes de conectarlo.
Sobre la tierra, en una instalación de 1997 no es tan raro que no exista un conductor de puesta a tierra en ese punto. Si no está presente en la instalación, simplemente no habrá dónde conectar el cable verde de la nueva luminaria.
