[LeJosie]

Reasons for the malfunction of all power windows in Emgrand EC820: 1. Due to deformation or damage of the window channel, or loose screws of the window regulator. 2. The grounding wire of the combination switch is detached, the main power wire is detached, poor contact of the relay, damage, or poor contact of the lock switch or failure to close it. 3. The window regulator is stuck. Below are precautions for car windows: 1. To prevent rainwater from flowing in, there are rubber seals on the window frames inside the car. When the glass is dirty, the friction with the rubber seals increases, affecting the operation of the windows, so the glass needs to be kept clean regularly. 2. Small cards are often inserted into the gaps of the windows. If not handled properly, the cards may fall into the door interior. The internal structure of the door is complex, and a series of chain reactions may occur if a card falls into the door, such as damage to the window regulator, door malfunction, or clogging of the drainage holes.
