=====================
STEP #1 - ALWAYS - check for DTC's - Diagnostic Trouble Codes -
include the DEFINITIONS - and whether the codes are C=Current or H=History -

connect a SET of AC gauges to the refrigerant part of the system -
set the cabin temp to 60* - full cold -
set the blower to a medium speed -
insert a thermometer into the LEFT/CENTER dash vent -
hold the throttle at around 2000 RPM -
close the doors -

post the
ambient air temp -
duct temp -
BOTH the HIGH side pressure AND the LOW side pressure readings -
