How Does The Rear A/C Work??.

The engine must be on as it pumps the refrigerant all the way to the back there is a seperate drain on the rear drivers side corner.

Does it share the same condenser as the front A/C??. Well really does it share all the front A/C's parts??.

I know that there is a fan/motor behind the plastic at the very rear of the drivers side - opposit the jack on the pass side.
There was a heater core lookin thin in there too and its plumbed under the van to the front A/C.

My reason for asking about the rear A/C is wondering if I could take the parts of one from a pick and pull and mount the outlets to the back wall for the planed sleeper that will go across the van right behind the front seats.The sleeper will be raised up appropriately to the conversion high top,so I could mount the components of the A/C under the sleeper.Run a separate compressor with a D/C motor so it would run independent of the engine running or not.Have a conversion for that D/C motor for a land line plug-in or off two deep cell "house" batteries or run when the engine is running.I already have planned to use a rear heat system mounting it between the two front seats below the sleeper.Nice comfortable cabin for "Ole Yellar" no matter what is happening outside.The Ole Yellar van is a A/C dash board van as well that I will restore during the build.
