FAW-Volkswagen Jetta vehicle , the vehicle air conditioner is in use following opening the radiator lover speed procedure , shut the air conditioning obd2 android supporter speed operation halt. After the ignition change is turned off , the fan velocity remains to be operating, take away the battery cable, flip the radiator fan stopped . Reconnect the battery cable, the fan is not jogging, but right after starting the engine and switch on the air-con , radiator admirer and ck 100 key programmer high-speed procedure . Transform from the engine and air-con , lovers however retained at high speed.

According for the vehicle circuit investigation, the radiator enthusiast velocity procedure ailments : Very first, the supporter F18 substantial temperature thermal switch get hold of closure ; Second, air-conditioning piping F23 high-voltage switch is closed . Test the radiator supporter thermal change , super vag k can get started the engine , open up air , in the event the radiator enthusiast pace when running, disconnect the thermal change wiring plugs, radiator supporter would not stop at high speed , the fault is not in thermal change . Unplug the air conditioner change F23 large strain piping connection plug , the lover stops , primarily air-conditioned high-voltage change failure. Just after starting up the engine and turn within the air-con pipe pressure exceeds 1600kPa, high-voltage switch F23 shut, air-conditioned high-speed relay , radiator supporter speed operation. Any time you flip off air-con and engine , 12V voltage within the 30th line fuse to admirer velocity relay get hold of closure radiator admirer low velocity admirer within the air-conditioned deceleration resistance to weakened high-voltage switch F23 substantial pace relay coil air conditioning , air con High-speed relay , radiator supporter velocity operation. Just after eliminating the battery terminal pace supporter relay contacts open up , immediately after reconnecting , contacts nonetheless from the disconnected condition, can not constitute the loop , hence the radiator enthusiast isn't running. Right after starting up the motor yet again as well as the open up air , autoboss v30 elite the failure to breed. Following the failure of this sort of high-voltage change F23 ruined, resulting in high-speed radiator lover is still functioning just after change off the engine . After replacing the high-voltage switches , troubleshooting.
