Just started getting a little cold down here in Florida and i tried to turn on my heat and nothing happened. Worked last winter and the winter before that. Was wondering what to test before i drop some money into her.

Make sure your cable is opening the door to allow the heat to come through. Then, if that works, I would make sure the thermostat is opening. If that's o'k, you most likely have a clogged heater core.

Blower works great on my yj but I'm not so sure on heat I believe I have either a clogged heater core as suggested or a bad core thoughts anyone?

Check on the firewall side Orange wire one bayonet clip is it hooked up? That is the blwoer motor hot wire. If not that pull the heater control panel and check the right side switch is working two white wires. Then check the resistor on the heater box right side passenger seat. Check for continuity there.
