I presume you now have a working blower on all settings as the resistor pack should have sorted this?

If you have no heat you first need to make sure the car is actually getting up to temp? If so then feel the pipes under bonnet going to and from the matrix with the engine @ running temp, they should both be hot to the touch. If not then look toward the heater valve or a blocked matrix which is uncommon unless the cooling system has been neglected.
