With my heater off the 2004 Ford Taurus runs great. About 5 seconds after I turn my defrost on I hear a short grind that sounds like a coffee grinder and my a/c compressor shoots liquid out the front bottom onto the engine. The fluid looks like it bubbles. It's a new a/c compressor and my windshield fogs on anything other than the defrost setting. I checked my heater core for leaks and can not find one. I definitely can see the a/c compressor shoot the liquid on the engine when it does that grind sound. Any or all help greatly appreciated.
