Well i got my heater core replaced all was good yesterday when i got it, but today after driving it something was wrong. After i turned off the ignition There was a noise coming from the heater core i believe it was, sounded like a motor was still on the only way i got it to stop was by disconnecting the car battery. Also i had my windshield wipers on full blast as it was raining in the morning but they came to they're resting point when i turned them off. Any idea of what it can be? I do have a warranty from the mechanic shop that replaced it. Also i wont have time to fix it till Friday and this is really buggen me seems like one problem is fixed and another one starts
