you have to remove the entire heater box assembly

 

Do you know were to start with that

 

drain the coolant , remove the heater hoses , remove the glove box liner , there is 1 hidden bolt insode the vent on the right side , it is a hook that holds the heater box up , loosen the bolt & carefully unhook it then undo the 3 - 7/16 nuts around the heater motor in the engine compartment & sldie the heater box back into the car now remove the vent & heat cables & remove entire heater box
