To make sure that engine will run stable when air-conditioner is work at the idling speed, and to lighten the load of the engine when accelerating(the throttle is open), the air-conditioning circuit is cut off. Daewoo ESPERO is installed with computer ECM control air-conditioner compressor and electric fans of condensers(see as Figure 26 and Figure 7). This circuit consists of low-voltage switch, high-switch, air-conditioner power supply relay, air-conditioner clutch and compressor electromagnetic clutch. The detection course of cooling fan control circuit is as follows:
