with an automatic AC control:

* Disconnect the small/rear connector on the liquid line to enable the fans full time. The
fans run continuously as soon as the engine starts - you need air flow thru the cooling
stack for the AC system to operate efficiently.

* if the system is really low on freon, the AC control will flash an LED, so you disconnect
the battery for a minute to clear error codes. Apparently the compressor may not run
if one or more codes are stored.

* connect a can of freon to the dryer(?) and completely open the can valve - freon will now be going into the system
at about 100 PSI - dunking the can in hot water will help speed the process. Remember to purge the
hose before connecting to the dryer.

* connect the battery and start the engine - the AC will be in the auto mode by default - set the blower speed
to 10 and the temp to 60.

* the compressor should be cycling or running full time by now. If cycling, the "on" time should increase to 100%.
If the freon level is too low, the system will set a code again and the compressor may not run at all, so you
add more freon and start over at step one.

* measure vent temperature - one can brought the temp down to 48 degrees with outside temp of 82.
This was with a system low enough to set a code and the compressor would not run.
