Why does the door unlock motor make a squeaking sound?
1 Answers
Door unlock motor squeaking is due to prolonged use, causing the hinges to make noise. At this time, adding lubricating oil can keep the pulley smooth and eliminate the noise. Additionally, the door and the car body are connected by a door stopper. Open the door to its maximum angle, clean the grease and dirt from the stopper arm, stopper pin shaft, and connecting bracket surfaces, then apply an appropriate amount of grease to the upper and lower surfaces of the arm to eliminate the noise. Also, check if the door seal has aged, as aging can cause friction noise. Cleaning the dust and rainwater from the seal gaps or replacing the seal can prevent aging.
