Why Won't the Wiper Return to Its Original Position?
1 Answers
If the wiper does not return to its original position, you should check whether the wiper is stuck or has an open circuit; check if the hardware is sufficiently lubricated; and inspect whether the wiper rubber is aged or if there is dust or other foreign objects trapped between the rubber and the windshield. The inspection methods are as follows: 1. Check if the wiper is stuck or has an open circuit: After confirming that the motor is functioning properly, proceed to check other potential issues besides the motor, such as whether the wiper has an open circuit or is stuck. These are relatively simple checks. 2. Check if the hardware is sufficiently lubricated: If none of the above issues are present, inspect whether the hardware lacks lubrication, causing excessive friction and preventing the spring from automatically returning to its original position. Apply lubricating oil to the surface of the card. 3. Check if the wiper rubber is aged or if there is dust or other foreign objects trapped between the rubber and the windshield: If the wiper's return is obstructed, clean the wiper rubber and windshield with a damp cloth. Replace the wiper or rubber if necessary. 3. Reset method: There are reset contacts inside the wiper motor. After turning off the wiper, the motor continues to operate until it reaches the reset contacts, at which point the wiper stops working. This point is where the wiper blade is at the lowest position on the windshield.
