2005 Canyon heat issue

Has anyone with a Canyon had the problem where their heat does not work? I have changed my thermostat with no luck. Heater Core seems to be fine since i am not leaking water anywhere but heat does not work. AC doesn't seem to work either but I never use that anyway.

Does the blower for the heat and A/C work? You might want to take a look and see if heat/cold is coming out of anywhere
