Smoke From The Dashboard
Smoke coming from behind the dashboard or out of the vents almost always means an electrical fault overheating, such as a short in wiring, a blower motor or resistor, or an accessory.
Critical risk
Stop immediately. Switch off, get everyone out and call for help if smoke continues.
Short answer · What should I do if smoke comes from the dashboard?
Pull over safely, switch off the ignition and get everyone out of the car. Do not open the bonnet if you suspect a fire under it. If smoke stops after switching off and nothing is burning, do not drive again until a professional has inspected the wiring. A smell of coolant mist from the vents is different; see smoke from air vents.
