Your heater core has gone out. It is located behind the dash board. They can be a real pain to mess with. Good luck!

It could also be your thermostat has stuck on open, not allowing your own r engine to heat up to optimal operating temperatures. This is cheap / easy fix, maybe fortune is with you.
