I just punched my car and it went to the redzone.. and when i turn my heater on... it didnt even work.. it just blew cold air... and the weird thing is... i popped my hood and it wasnt hot? Well i ordered my fluidyne and fan... mvp motorsports.. btw cheapest place i've seen... well back to the topic... what could be wrong with the heater and cooling? thermostat? should i flush my radiator and redo it? thanks...

 

Sounds like you have a Heater control Valve stuck of broken it's located on the firewall behind the intake manifold.
