What Causes Smoke and a Burning Smell from Car Air Vents?
1 Answers
Smoke and a burning smell from the car air conditioning are likely caused by a loose connection in the blower motor or speed control resistor circuit, leading to overheating and burning. Below are the specific reasons and solutions: 1. Dust clogging the air vents: Due to electrostatic adsorption and repeated air circulation, a lot of dust from the air accumulates in the vents. Without deep cleaning over time, this can breed bacteria and viruses, and even reduce cooling efficiency in summer, increasing fuel consumption. Solution: Clean the air vents promptly. 2. Overheating of the blower motor or speed control resistor circuit. Solution: Turn off the air conditioning and visit a repair shop as soon as possible to identify the exact cause. Continuing to use the air conditioning poses a fire hazard.
