heat

[mista_sup]

what causes heat to blow through the vents while driving when the heat is off.. its not like the heat is on but u feel a little bit of heat while driving????????????

im guessing the vent does not 100% close. could be debris stuck in there or faulty motor. its either the hot air from the engine or from the heater core behind the dash.

Turn you heat to cold before you turn off the fan and it should blow cold, I don't think I've owned a car that completly shuts off air when fan is set to off.
