Freon has nothing to do with the defrosters----defrosters run off of the heater and the only relationship to the a/c is they both use the same blower usually--but not always.
Just curious, then why does the air-condition compressor come on when using the defroster? (on cars)
MM.
The compressor is used to dehumidify the air for defrosting both my cars and my class A gasser.
But what do I know
Autos use the compressor. A Lot of Motorhomes also, but not all. What I found curious was his statement about 2 blower motors. UNLESS you have an overhead defroster system the SAME motor operates all the dash AC systems. The Motorhomes I have worked on, the same blower motor operates the Defroster and dash system. Some motorhomes(Newmar's and some Monaco's were 2 ) had an overhead blower system separate from the dash AC/defroster system, to help blow air DOWN from the overhead. Doug
