Why Can't Car Windows Be Fully Lowered?
1 Answers
There are several reasons why car windows cannot be fully lowered, including damage to the window lift motor, poor contact in the electrical control wiring, motor overheating protection, excessive resistance in the glass guide channel, or loss of computer data. Below are specific explanations of different window-opening methods: 1. Leaving a small gap on one side: Opening a slight gap on one window allows cigarette smoke to dissipate faster without blowing onto rear passengers. 2. Opening front and rear diagonal windows simultaneously: While driving, opening diagonal windows causes incoming airflow from the front window to interact with the rear window's airflow, reducing driving noise. 3. Closing only one front window: Closing one front window while opening the other three creates highly unbalanced airflow with clear directional movement, quickly removing odors but causing noticeable wind pressure for rear passengers. 4. Opening both windows on the same side: This causes strong airflow to enter directly on one side, creating particularly strong wind pressure for passengers on the opposite side. At high speeds, this method makes steering difficult and is not recommended. 5. Opening all windows completely: Opening all four windows floods the cabin with air, maximizing airflow at exhaust vents and creating turbulence that may displace lightweight objects in extreme cases, posing driving hazards.
