Solutions for a car door that is difficult to open: 1. Spray liquid lubricant on the hinges of the car door. 2. Clean the grease and dirt on the surface of the limiter arm, limiter pin shaft, and connecting bracket, and apply an appropriate amount of grease on the upper and lower surfaces of the arm. 3. Wrap some tape around the door latch. 4. Replace the door seal. The following are the reasons why the car door is difficult to open or close: 1. There is significant friction between the door handle lock and the lock post, and prolonged use leads to poor lubrication. 2. The door lock post is misaligned. 3. The door hinge is rusted or deformed after long-term use.
