First of all, we understand the working principle. The wiper motor is driven by the motor. The rotary motion of the motor is converted into the reciprocating motion of the scraper arm through the linkage mechanism, thereby realizing the wiper action. Generally, the motor is turned on, and the wiper can be operated. By selecting the high speed low speed gear, the current of the motor can be changed to control the motor speed and thus the scraper arm speed.

1. Confirm the connection mode and specifications of the wiper motor. The struts are connected to the wiper rocker arm, and some of the arms are fixed to the rocker arm by screws, and some are locked by the male buckle.

2. Whether the rubber strip of the wiper motor is aging. Pull the wiper motor up and use your fingers to touch the cleaned rubber wiper strip. If the blade ages, hardens, or cracks, the wiper motor fails.

3. Whether the wiper motor maintains a certain speed at different speeds. Place the wiper motor switch at various speed positions, especially if the wiper motor maintains a certain speed during intermittent operation.

A radiator cooling fan is device that can help regulate engine temperature by pulling air through a radiator. If your electric fan is failure,the temperature of the hood will be higher.what's worse,it may make the engine out of work.Replace the electric fan on time is a way to protect your vehicle. JX fan can make your traveling more safer.Ideal replacement:this engine cooling fan assembly was precision-engineered to match the fit and performance of the stock radiator fan assembly on specific vehicles.Keep your engine cool.Also allow quicker warm ups and cool downs, longer water pump life, less fan noise, improved air conditioner performance and improve gas mileage.Quality assured - motors are tested in laboratory settings to ensure; performance.All units are test: fitted onto the corresponding radiators prior to release to ensure precise, consistent fit.Cost effective and reliable.Comparable, perfectly balanced unit ensures ease of installation.
