So my Evo ever since I bought it has been stuck on full blast heat and it’s always stuck on the dash. Was wondering what I should start to look for before taking it in! HVAC has never been my strong suit for vehicles! I also just changed the knobs out and still have the same issue. Thank you!

The heat is controlled with a blend door which has an actuator that diverts the blower air into the heater core, or not. But if it's also stuck on dash, the HVAC control circuit board or some other CANBUS component could have failed. Get someone with a code reader that can read the CANBUS controllers for errors to find out more.

Ended up figuring it out, turns out a plug for the hvac controls and a plug on the radio are the exact same plug so whoever took it apart simply put it together wrong and all I had to do was switch the plugs around, hope this helps someone
