Why is there water leaking under the steering wheel?
2 Answers
Water leakage under the steering wheel may be caused by a blocked drain pipe of the air conditioning evaporator. You can go to a 4S shop or auto repair shop for inspection. Related information: 1. Correct steering wheel grip: Sit upright and hold the steering wheel with both hands at the 10 and 2 o'clock or 9 and 3 o'clock positions. While driving, do not operate with one hand for a long time unless necessary, and do not rest your hand on the gear shift or window frame for extended periods. 2. Steering wheel composition: The frame is usually made of zinc alloy or aluminum alloy. Some manufacturers are experimenting with cheaper and lighter magnesium alloy. The frame is produced by die casting. A few manufacturers still use steel sheet metal for the frame, which has a complex structure.
I've been driving for over twenty years and have encountered water leakage under the steering wheel a few times. The most common cause is improper drainage from the air conditioning system. When the AC is on, moisture generated by the evaporator should flow outside through the drain tube. If the tube gets clogged, cracked, or detached, water accumulates in the footwell area under the steering wheel. Another possibility is aging windshield sealant, allowing rainwater to seep in and pool at your feet. Don’t underestimate this—water leakage can soak the carpet, potentially causing electrical shorts or long-term rust, compromising vehicle safety. I recommend checking if the carpet is wet first. If it’s AC condensation, the water is usually clear. If it’s colored or sweet-smelling, it might be coolant leakage—stop driving immediately and address it. Regular maintenance, like cleaning the AC drain hole (typically located near the front of the engine bay), can prevent major issues. If you can’t handle it yourself, consult a professional mechanic.
