Reasons for Non-Responsive Window Switch After Water Ingress

Window malfunction reasons may primarily include circuit failure; deformation or damage to the window channel; loose screws on the window regulator; damaged window regulator; or misalignment of the guide rail installation. For restoration, it is recommended to visit a professional repair shop. Here are some maintenance measures for the window system: 1. Regular Window Cleaning: During daily use, windows are exposed to sun and rain, inevitably accumulating dirt. Excessive dirt can increase window lifting resistance, accelerating wear on the motor or rubber seals. 2. Inspect Window Rubber Components: If rubber components are not maintained periodically, aging or cracking of the rubber parts on the window may affect glass support and sealing integrity.

What is the original spark plug model for GAC Trumpchi GS4?

Trumpchi GS4 uses NGK brand iridium spark plugs with the model number 454523. The benefits of replacing spark plugs include improved vehicle performance. Spark plugs are consumable parts that require regular replacement. If spark plugs are damaged, they can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most notably, difficulty in starting the engine, affecting normal vehicle use. Severe spark plug erosion, such as scarring at the top, damage, or melted electrodes, indicates that the spark plug is damaged and should be replaced. Spark plug location: Spark plugs are installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition cables. Over the past decade, most car engines have switched to direct connection between the ignition coil and the spark plug. Spark plug replacement interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the user manual. Generally, platinum spark plugs should be replaced every 40,000 kilometers, ordinary nickel alloy spark plugs every 20,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers.
