Test conditions conditioner efficiency
All vents should be open. The engine must be warmed up and work on a speed of about 2000 min-1. The fan has to operate at high speed '4'. Handle the thermostat must be set to position ?«COLD?». Switch "Max A / C" must be set to position ?«On?». The glass in the door should be lifted, the doors are closed. Temperature readings should be read on the left ventilation duct when the compressor.
