Check your passenger seat carpet. If your heater core is leaking, it usually pools in the passenger seat footwell.
If its dripping off the fan motor, then your leak might be RIGHT AT the heater core fittings going into the cab, and then dripping down onto the fan motor.
You may need to get the engine up to full temp, then open the hood and see if its actively dripping from somewhere. At full engine temp, your coolant system will be near 15psi of pressure, and that could open up a pinhole, or force fluid past a small leak that a cold engine wouldnt.
But yeah, my money is on heater core. Easy to change.
This was helpful thanks a ton.
