if i turn my car on without starting the engine, can i run both of the seat warmers and also the electric rear window defroster without running the engine?

Typically no. There are separate buttons for the windshield defroster and the rear window defroster. On some cars, the heater may turn on while the temperature control is set to "auto," but you can still turn it off on your own.What is a rear window defroster?In order to defog the rear window and melt frost, snow, and ice, it must be turned on, which activates a grid of wires that may be seen as thin lines on the inside of the glass. The majority of rear defrosters run on a timer that, after around ten minutes, turns the defroster off automatically.Typically, the front window is heated with hot air from the main heating system, which is heated by the engine coolant, and the rear window has an electrical resistance heating element connected to the glass.The primary reason is that, since the heat exchanger for the cabin heater is frequently located directly behind the dashboard, it isn't particularly practical to duct hot air all the way to the back.Although less popular because it requires the use of extremely small wire in order to avoid obstructing visibility, some automobiles also have electrically heated front windows.
