Possible causes of smoke coming out of vents in a car

There are several potential causes of smoke from a car’s vents. Understanding these causes can help you determine the best course of action to take if it happens to you.

Overheating engine

An overheating engine is one possible cause of smoke coming out of a car’s vents. An engine can overheat for various reasons, including a malfunctioning cooling system, low coolant levels, a faulty radiator or water pump, or a clogged thermostat.

Electrical problems or a short circuit
