Why Can't the Car Hood Close?

[RachelRose]

If the car hood cannot close, it might be because the release lever inside the cabin is stuck and hasn't returned to its original position. Here is some knowledge about car hoods: 1. Structural Composition: The engine hood is generally composed of an outer panel and an inner panel, with heat insulation material sandwiched in between. The inner panel enhances rigidity, and its geometric shape is selected by the manufacturer, typically in a skeletal form. 2. Open State: When opened, the engine hood usually flips backward, though a small portion flips forward. A backward-flipping hood should open to a predetermined angle without contacting the windshield, maintaining a minimum gap of about 10 millimeters. To prevent accidental opening due to vibration while driving, the front end of the engine hood is equipped with a safety lock hook mechanism. The lock release switch is located under the dashboard inside the cabin, and the hood should lock automatically when the doors are locked.
