Default A/C wont blow heat

i have a 99 ex v6 203k miles. Its old but i love my car. My heater stopped blowing hot but the heater core was replaced about a year ago. the cold still works perfect. Is this a simple fuse problem? any help would be great

Please read the rules and that in each section. The DIY Area is not the place for this question, I have moved it.

If you had the heater core replaced, I'd start with checking the cable to the heater control valve and be sure it is moving. If so, check the temp of the hose on both sides of the valve....it can fail internally meaning the cable moves but the valve doesn't open.

Could also be a thermostat stuck open too. I had one stick on me and the air would blow luke warm but never hot.
