I heard somewhere that vehicles need the air condition compressor or the air condition to be working in order to be able to defrost the windows. Is this true.

Of course not - many vehicles don't have AC.

 

The AC dries the air which makes the defrost work a little bit better. It also serves to keep the oil in the AC system circulating and the bearings from being damaged by months of non-use.
