What are the causes of a faulty driver's door contact switch in Volkswagen vehicles?
1 Answers
If the door contact switch malfunctions, disconnect and reconnect the battery cable. If this doesn't resolve the issue, replace the door contact switch. Below are specific details about door contact switches: 1. Installation Location: Mounted in the door gap area, pressed by the door frame when closed and released when opened. Its function is to detect the door's open/closed status and provide status signals to the vehicle's control circuit. It can be used to control features such as reading lights, dashboard door status displays, and door open warning lights. 2. Structure: The car door structure is relatively complex, containing numerous components. 3. Function: The door and body are connected by hinges and limiters - the former serves a fixing purpose while the latter restricts the opening angle of the door. Strong impacts can easily damage these two components, causing permanent deformation and displacement of the door.
