Like the title says only coming from the defrost and floor vents no matter what setting i have it on. Ive heard it might be the heater core, vacuum lines, or clogs. If it helps sometimes i smell coolant but only a lil bit. Any step in the right direction is appreciated.

 

I would check the vac first since that is what the car uses to move the flaps, or whatever they are called, from one position to another. I have had a couple vehicles in the past that have had issures with this and both of them, it turned out to be the selector switch on the dash that was leaking.

 

i agree with checking vacuum lines.

 

where would i find these?

 

Some vac lines are out under the hood, black plastic lines then some are behind the control ***** in the dash. Listen for leaks around the heater control **** too.
