The rear defroster could be the relay. Make sure the fuse is good.
The engine is another question. Make sure the power steering fluid is full, and using a stethoscope, check the alt, water pump, and power steering pump for noise. It could be a bearing. If you have no luck, check for a vacuum leak that could cause a noise.
Let me know what you find.
