It sounds like you have a very tight running or bad a/c compressor since most all systems will engage the compressor when the defroster is on...............
It depends on the vehicle and if it is on the right side or left side.
Not sure what a defroster resister is, need more info please.

As you drive the steering tightens. You may need to check your power-steering fluid or put air in your tires.
A wrench tightens bolts. The mechanic across the street from me.
On the drivers side of the instrument panel ( it must be somewhere behind the steering wheel )
To install a hardtop defroster on a 1997 Miata, first, ensure you have the necessary wiring harness and switch. Begin by removing the interior trim from the rear window area and connecting the defroster wiring to the existing harness, making sure to secure any connections. Next, mount the defroster grid on the inside of the hardtop rear window according to the instructions, ensuring it adheres properly. Finally, reinstall the trim, connect the switch to the dashboard, and test the defroster to ensure it functions correctly.
It is probably the sound of the defroster fan.
what are the colors of the wires for the rear window defroster coming from the rear window to the defroster bottom ? can any body help me
What your seeing is the cars radio antenna. Your defroster is on your back window.
There should be a connector in the back left(driver) side of the wheel well area. inside the vehicle.
There can be several reasons a rear defroster fails even when the light on the defroster switch indicates it is on. The most likely reason is that one of the metal defroster tabs along the side of the back window has separated from the defroster. If the defroster tabs check out as still attached to the defroster then you need to do a little checking with a volt meter. The first thing to check is the voltage directly on the tabs themselves. This should be around 12-14 volts. If the voltage is zero then there is very likely a broken wire someplace between the defroster relay and the defroster. If you have 12-14 volts a the defroster tabs then there is something going on with the grid which is normally broken defroster elements, those long thin horizontal lines on the back window.
