heat getting into car

when i drive fast (as on the highway), i feel heat coming in from the air vents even if theyre closed. Seems like either my heater is always on or heat from the engine is getting through the firewall. But, my guess is that the main problem is the heater (feels like heat from a heater, smells like it too). I think im gonna get another A/C control unit (some of the functions dont work anyway), but is there anything else I should look out for? I mean I only feel the heat when I drive fast, as the A/C control unit works independently of the movement of the car, so how are these related?
