You're going to have to be more detailed than that.

Do you mean the blower is running constantly and won't shut off or is it just heated vent air coming in

It is just hot air blowing through the vents.

Do you have control over temperature when you are operating the system?

You should be able to put the air door for max AC/recirculate in the recirculate position to shut off outside air.

The door is behind the glove box so you can make sure it is actually closing.

That door is closing on its own.

That is the only opening to the outside so if you are getting air when that is closed, the fan has to be running.
