When using the wiper, if the wiper motor makes abnormal noise, especially if the wiper motor makes a "buzzing" sound but does not turn, indicating that the wiper mechanical transmission part has rust dead or stuck place, then the wiper should be shut down immediately to prevent the motor from burning out. If there is no abnormal noise from the windshield wiper motor, the windshield wiper does not work, mostly because the fuse has blown out. At this point, just find the wiper fuse, pull out and replace it with a new one. If do not have special wiper fuse, also can replace with other thing. Sheet fuses can be replaced by fuses on other secondary lines, and glass tube fuses can be replaced by a few turns of the tin foil in the cigarette case against the outer glass tube.

If the light rain, the windshield wipers can not thoroughly clean rain, uneven wipe traces left on the surface of the glass, in general, this is because the wiper rubber parts hardening, wiper can't fit closely with the glass surface, or because the rubber on the wiper has the wound lead to wipe on uneven, forming residual dirt. It's best to buy a new windshield wiper or rubber sheet. If the windshield and wiper blade are fogged, beaded, streaked, or locally blurred by oil film, dirt, or wax when the wiper is working, simply clean the windshield and wiper blade.
