I reinstalled a ceiling fan from the basement. When it was down there all 3 speeds worked fine. Now that I've reinstalled it upstairs, it only runs on high speed. The are 4 wires from the fan, white black blue and green. Green is ground, blue is for the light, white neutral and black hot. 3 wires from ceiling, white black and green. Help!

If blue is for the light, and black for the fan, then connect both to black, white to white, and green to ground. Then however you switched the fan speeds before should continue to work. Were there more wires to the fan in the basement?
