True. Most car heaters bleed heat from the engine. Only a few have actual electric heaters..

Air conditioning acts as a dehumidifier, reducing the moisture content in the atmosphere. Irrespective of the temperature, it will significantly remove the condensation from a windscreen.

but you still have to have the engine running to run the little engine for the air conditioner

didn't you realise that air conditioners in cars have their own engine hence the little tiny exhaust at the back ,thats why running aircon uses so much petrol because your feeding 2 engines

Yes I was going to say that it has been illegal to leave a car running here in the street in glasgow for a few years now.

I have no idea if its a country wide law or just a law enforced my councils.

This is an exchange about the amount of time it takes to clear a widescreen. The assumption has already been made that the engine is running.

The air condition system does not have an "engine," it uses a compressor, which is driven by a belt from the crank pulley. An engine is a machine that uses compression to produce energy or power.
