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.
