The horn switch and relay may fail to separate after prolonged use, causing the car horn to keep sounding. In this case, you can remove the main airbag on the steering wheel to check the condition of the contacts. Locate the horn relay in the engine compartment fuse box and check whether the relay is properly closing and opening.

Methods for Repairing Plastic Dents on Cars

Methods for repairing plastic dents on cars are as follows: 1. Use hot water: Plastic softens when heated, and dented areas can be popped out by applying heat. Once the dent returns to its original shape, immediately cool the area that was exposed to hot water with prepared cold water to allow the rubber to contract and recover. 2. Use dent repair tools: Although bumpers are highly malleable, sometimes the force from hot water expansion alone is insufficient to lift and repair the dent. In such cases, external force is needed, and dent repair tools can meet this requirement, being very effective for small dents. 3. Apply manual pressure after relieving tension: Try removing one of the car's screws, reach inside the bumper with your hand, and apply pressure from behind. This can also help restore the bumper. However, dents in the bumper are often accompanied by scratches, in which case a visit to a repair shop for repainting may be necessary.
