I want to replace the fan motor with a 2 speed one

i want to add a switch to the furnace so i can have the fan on all
the time in slow speed. then when the burner or the ac comes on
it will change to high speed.

I think many (most? all?) furnace/AC combinations already
incorporate dual speed fans. Are you sure it doesn't already have
the capability you seek? You might just need an appropriate
thermostat.

I believe you are correct. The heat uses the low speed and the AC
the high one.
