What Causes the Dashboard to Have No Power When the Car Key is Turned On?
1 Answers
When the car key is turned on and the dashboard has no power, it could be due to a damaged dashboard, a depleted battery, or poor electrical contact. Below are detailed explanations of the causes: Damaged Dashboard: The dashboard illumination light may be damaged. To fix this, remove the dashboard; the illumination lights are usually located at the back. Replace any non-functioning lights. If the dashboard's power supply wire is broken, check for any short circuits or disconnections and repair them if necessary. If the dashboard's power supply fuse is blown, inspect and replace it if needed. Depleted Battery: Using onboard electrical devices for extended periods after turning off the engine, such as running the air conditioner, charging a phone, leaving the headlights on, or playing the stereo, can drain the battery. To prevent this, avoid using or continuing to operate onboard electrical devices after turning off the engine. If the vehicle is parked for a long time, the battery will self-discharge, gradually losing power. To address this, start the vehicle periodically to recharge the battery, ensuring the engine runs long enough; otherwise, the charge may not be sufficient to start the engine. A depleted battery can also cause the dashboard to remain unlit, so replace or recharge the battery promptly. Poor Electrical Contact: Poor contact in the dashboard's wiring can also result in the dashboard having no power when the car key is turned on.
