anyone know where/how to remove the heater core for a '03 wrx? i did some looking around the car and think it is under the passenger side dash where the fan is at. just looking for a point in the right direction. :tia:

I think its a pretty major job and requires the dash to be almost fully removed. Located right behind the lower center dash inside the heater and cooling Unit. Loosen the screws on the left hand side of the heater/cooling unit to remove heater core cover.
