What Causes a Car Air Conditioner Fuse to Keep Blowing?

[LeHaven]

If the fuse keeps blowing, it may indicate an abnormal circuit condition, and it is recommended to contact the nearest service station for inspection promptly. In a car's electrical system, numerous electrical devices are connected by wires of different colors, among which the fuse is the most critical component not to be overlooked. The reasons for a car fuse blowing are as follows: 1. Improper sealing of the fuse box: When cleaning the engine compartment, due to improper sealing of the fuse box, remember never to rinse the fuse box directly with water, as this can easily cause a short circuit in the fuse, leading to malfunction of the entire vehicle's electrical components. Most fuse boxes have a prominent sign prohibiting water rinsing. 2. Excessive power supply: When replacing headlights, an excessive power supply can easily blow the fuse. In such cases, immediately replace the fuse with one of higher current rating and the power cable to prevent excessive current and overheating. 3. High-power audio systems: These may also cause the fuse to blow. When installing high-power electrical devices, always pay attention to the current level and promptly replace the corresponding fuse. Most reputable modification shops are aware of this issue.
