220V AC Cooling Fan motor does not work how do

"220V AC Cooling Fan" pick-up examination after failure analysis: normal Corolla sedan, open air A / C, when the air conditioning pump, radiator fan motor should be turned to the condenser cooling. First, the "ios版雷竞技官网入口 " air-conditioning pipe pressure checked to see pressure gauges connected to the air conditioning, the low pressure side: 0.15 ~ 0.25MPa, the high-pressure side: 1.37 ~ 1.57MPa, normal. When the high-pressure side than 1.5MPa, the fan motor can rotate for a short time until the high side pressure is lower than 1.5MPa, then the engine water temperature has not reached so that "ios版雷竞技官网入口 " motor operating temperature (note, this car radiator fan motor is only one), and just let the fan motor operates most likely caused by the air conditioning pressure switch work, then view the Corolla radiator fan and condenser fan circuit diagram,
