Speaking wipers, may be a lot of riders did not mind. The sum of an automobile, the wiper is a relatively small component. But according to an International Driving Safety Survey: driving rain, accident rates caused by aging wipers about five times higher than usual. Recently showers frequently, if you have any wiper failure, we must hasten to repair or replace.

  Generally, there are two types of wipers, intermittent one is the traditional type, which is the most common wiper, there are three sections to four, ranging from drivers to make adjustments in accordance with the rain and the sight of the situation; the other is the raindrop-sensing in recent years, more use in the class models.

  4, during the test, the wiper switch is in various speed position, it is checked whether the wipers at different speeds to maintain a certain speed. Especially in the intermittent operation state, but also pay attention wiper movement is maintained at a certain speed.

  5. Check wiper status, and Wiper strut swing uneven or missing scratch phenomenon exists. If the following three cases, the description for this wiper failure. One swing flow, wiper abnormal beat; the second is in contact with the glass surface of the rubber surface can not be completely fit, wipe the residues generated; the third is to wipe the glass surface after water film presents the state, resulting in fine streaks on the glass, fog and linear residues.

  6, the test should pay attention to any abnormal motor noise, with particular attention when the wiper motor "buzzing" sound without rotation. This shows that the wiper mechanical transmission parts have rusted or stuck in place, then immediately turn off the wiper switch, to prevent burning motor.

  7, some people think that the longer the length of the wiper blades, the brush area is larger, better vision. In fact, wiper-chip is not the better. Although the length of the wiper blades longer horizons can increase the visible range, but also increases the relative burden wiper motor, wiper rod.
