Blower motor replacement 3 speed to 2 speed - Help

My 3 speed fan motor stopped working and I'm trying to replace it with a 2 speed. This happened in the summer and it appeared to work fine for AC. However, now that it's winter, the blower does not blow when the heat is on. Everything else seems to work properly. What should I do?

Dont know what kind of furnace you have, but typically the cooling speed is different than the heating speed and each one has their own relay. If you turn the fan to ON at the thermostat it should run cooling speed and allow you to at least heat the home.
