the heater cole
Around $800 which I did myself and wish Ive paid the $800. It took me 6hrs to take out the Heater core with some help from youtube. Now heat wont blow from the front vents ( motor vale or temp control switch probably went bad )
My labor guide says it is about a 9 hour job if you have air conditioning to replace the heater core parts would be another $175 or so.
