Typically the four thermostat wires are:

R = power (or common)
G= FAN
W = Heat
Y = Cool

Assuming that you have a normal electric or gas furnace and air conditioning, if the heat really is coming on, then just switch the position of the the Yellow and White wires.

After switching from heating to cooling - air won't come on


It sounds like the fan relay in the stat itself is not closing when you make the switch over. If you have had the stat for less then 5 years it is covered. Honeywell has a full 5 year warranty on their focus pro stats, and would replace it free of charge.
