What to Do When the Reversing Camera Gets Blurry Due to Water Ingress?
3 Answers
If the reversing camera becomes blurry due to water ingress, use a hot air blower to blow air at the camera for a few minutes to remove the moisture inside. Below are the causes and solutions related to water ingress in reversing cameras: General Water Ingress: First, wipe the camera lens clean with a dry cloth, then use a hair dryer to blow air at the camera for a few minutes (alternating between hot and cold air). This method is effective for minor water seepage. Water Ingress Due to Poor Sealing: If the water ingress is caused by poor sealing of the camera, it is best to remove the camera, dry it thoroughly, and then apply sealant to reinforce the sealing to prevent future issues. Water Ingress into Internal Components: If moisture has penetrated the internal components of the camera and the hair dryer is ineffective, it is necessary to visit a repair shop for a replacement.
When the reversing camera gets blurred due to water ingress, I usually start with simple steps: stop the car immediately, turn off the engine, and gently wipe the lens surface with a clean, soft cloth to see if the moisture can be removed. If it remains blurry, water might have entered internally, requiring disassembly—use a hairdryer on low heat to blow warm air at the camera for 5-10 minutes or place it in a bag of rice overnight to absorb moisture. Also, check the sealing ring; if it's damaged or deformed, replace it or temporarily seal it with tape. To prevent this, I avoid driving through water in rainy weather, park in dry spots, and regularly clean the camera and inspect the seal. If DIY efforts fail, don’t hesitate—head straight to a 4S shop or repair shop for a replacement, as reversing assistance is too crucial to compromise safety. Overall, the DIY process isn’t hard but requires patience.
Blurry camera due to water ingress is a common issue. I would take immediate action: prioritize safety by pulling over to inspect, first wiping lens surface moisture with a dry cloth. If that doesn't work, use low-temperature warm air to blow gently for a few minutes or remove the camera to air-dry in a ventilated area for 24 hours. For prevention, avoid directly spraying high-pressure water at camera areas during car washes and park away from waterlogged roads. This malfunction may relate to aging sealing rings - inspect and replace rubber gaskets if needed. If DIY solutions fail, I recommend promptly visiting a professional shop for repair or replacement parts - never compromise driving safety. Develop regular maintenance habits to prevent recurrence.
