    Heater Core I'm guessing. I had a sebring coupe that would do that. Made it hard to defrost my windows. I got my coolant flushed and it took care of it for a while. Problem came back though.

    Your problem could be something completely different. These sevilles are their own breed.

    Check the water pump belt tensioner. Then check the purge line.
