Water treatment of wiper motor

In most repair shops, we can often find that many car owners come to repair the wiper motor, especially when there are some thunderstorms. There are a lot of water failures in the wiper motor, which is a common fault in auto repair shops. Water entering the motor will directly cause the motor to fail, which not only poses a hidden danger to driving safety, but may also cause damage to the car in the long run.

     The following editor will share how to deal with the water ingress of the wiper motor:

     1. Water ingress due to the failure of the seal at the motor cylinder head is mainly caused by the failure of the seal ring, which may be due to the unreasonable design of the seal groove and seal ring. For this fault, the wire diameter of the rubber O-ring can be increased.

     2. The main reason for the failure of the seal at the harness guide sealing ring to enter the water is that the design of the wire sealing ring is unreasonable, and water enters the motor through the wire sealing ring. The wire at this place is directly connected to the inside of the motor. Waterproof sealing is very important. The sealing ring must be interference fit with the hole. After the wiring harness is installed, waterproof sealant must be applied.

     3. The sealing failure of the gearbox rear cover and the water ingress are caused by the material problem of the gasket. The motor uses plastic gaskets, and the improved rubber gaskets can solve the problem.

     The above are some solutions to the water leakage of the car wiper motor. I hope to help you in a limited way.
