Heater core install

Hi and thanks for using 2CarPros.

I need to know if this is a Cherokee or a Grand Cherokee. Also, do you have the pictures of the parts? I didn't receive them with your post. I attached three different pictures of the HVAC heater/AC box. I don't know if it helps, but it's for the Cherokee and not the Grand Cherokee.

Let me know if this helps or if you have other questions. Also, if you have pics of the two parts left over, it will help.

Take care,
Joe

Hi Eric:

Is that a hard plastic or more like a gasket? Take a look at the attached picture. Could it belong at the top of the blower motor side as a gasket? Also, on the right side, I believe there is a rubber gasket type component that goes between the two cases to prevent air leaks.

Let me know. If what I just said doesn't make sense, attache another picture of the component flipped over.

Take care,
Joe
