Sounds like it's probably a heater core. If there is no heat at all it probably has a blockage... or less likely in your case, a severe leak; check for coolant around passenger floor board. If you disconnect the two heater hoses and pump water through one and it comes out the other, it is not blocked. If no leak is present as well, it could very likely be the temperature change slider in the dash. Hope this helps you a bit.
