Heater core is good, but no heat goes to defrost and all other positions, but no heat good. Heat goes in the heater core hose from engine but does not heat, and the heater core outlet hose is cold did a complete flush of the system. So, where is the blend door located on the car listed above (Touring)?

Hi,

If both heater core hoses are hot, then there is heat into the core/cabin. It isn't making it into the passenger compartment which is likely a faulty blend air door as you mentioned.

To get you started, here is a link that explains in general how one is replaced. You can use this as a guide.

If you look at the attachments below, they are the directions specific to your vehicle for the replacement.

Let me know if this helps or if you have other questions.

Take care,

Joe
