What setting was the vent selector on?

yeah. does the clicking sound like it could be coming from the head? if so, check your oil. if the oil is low and you add some and the clicking in the head doesnt go away, youve got bigger problems

but it only happens when the heater is on? i guess im confused.

then it could be something in the blower motor. if you need one im parting out a 2001 ex coupe

Yea it could be bad valve lash. Have the valves adjusted.

thats not bad thinking, but it only happens when the heater, as in the heater that warms the car up is on. i think its something to do with the blower motor. also, checked it out, it happens when the ac is on also
