It is probably the sound of the defroster fan.
Electrically heated seats, wing mirror defrosters and rear window defroster.
Pour hot water (not boiling) over the key hole and door seams, gain access immediately and turn on defroster and turn heat
It should if the system is in good working order.
The 1953 Lincoln was the first car that had a rear window defroster. It also was the first car to have an optional 4 way power seat.
that would be the car turning because the car that had to swerve to avoid it hit another vehicle due to the turning car's failure to yield.
First you start the car. Then you let it idle or drive it until it reaches operating temp. Finally you turn the heater on to the defrost setting.
The engine would heat up quicker without the heater on but ever so slightly, so it probably doesn't matter.
This is to provide electrical current to heat the thin strips.
that would be the car indicator signal! that tells other drivers which direction your turning!
If you have the defroster in the on position the ac will do that.

Because it's not a defroster button! It's just the symbol for ventilating the air into the car. It shoudln't be called a defroster since defrosting is meant by heating up the coils that you see at the back of the car. I'm pretty no car has wires in the front!
it is probably a bad heater core
thermostat is frozen.
Turning the heat on would actually lower the engine temperature. It's a well known trick if your car starts to overheat. Having the A/C on causes a power loss to operate the compressor, which would also cause engine temperature to go up due to the hot air from the condensor going through the radiator.
NO the heat would be to strong and the insides where the heat comes out would melt!!!!!!!!!!!!!!!!!!!!!!
That would be the inside diameter of the circle created by turning the steering wheel completely left or right.
When the air conditioner comes on, which includes turning on the defroster at low temeprature ranges, it draws a lot of power from the engine. This can result in a decrease in idle speed and less available power on starting off from a start. This is often felt as a shaking or jerking. It is possible that the idle is low or that there are problems preventing full power.
Is it a loud thump like something has hit under the car?
Only if your defroster uses the A/C, otherwise heater will not effect gas mileage. The heater uses the waste heat from coolant used to cool the engine, so has no extra load on the engine. The heat was going to waste anyway. You are just diverting it into the car instead of outside.
Defrost the windshields so you can see where you are going. Useful in icy climates.
Which heat shield? There are several.
The night before, when you park your car, face it towards the east. Run the defroster full blast on its highest setting for 4 minutes before turning off the car, and then ge tout quickly to trap the heat inside. Finally, right before leaving the vehicle, climb on the hood and lick the entire outer surface of the windshield. This will keep frost from forming in the morning and you will have a perfectly clear windshield.
Well, on part is the engine. It makes so much heat, there is a fan in it to cool it down. That is why whenever you start a car, it shakes. That is the fan turning on.
