I have a 2003 Chrysler Sebring 4-door sedan with a heating problem. At first we thought it was a heater core issue but it turns out the hose that runs from the heater core had been damaged. So my husband took the old hose off and is trying to replace it but he has no clue where the other end goes? Could someone please tell me what this part is/what "system" it is a part of so I can take it to a shop as I have no heat whatsoever and well, its almost December.... in Michigan.
