[DeTomaso] front condensor question

[Scott Bell]

You need the fans running with the AC on because when the car is stopped, the pressure in the AC system will continue to build
because there is no cooling happening without the fans running. This will cause the system to go into an overpressure situation
causing the trinary switch to shut off the compressor or a hose to blow if there isn't a safety pressure switch installed in the
system.

>>>You would definitely want the fans to be triggered by the radiator 
thermoswitches OR by the A/C.   Most conventional cars with front-mounted A/C 
turn on the radiator fans the moment the A/C system is engaged regardless of 
engine temp.

Without anything scientific to back up this suggestion, I would think it 
would be advantageous to have the A/C system turn both fans on at the same 
time; however having the radiator turn the fans on sequentially saves wear and 
tear on the #2 fan, perhaps?
