Why are your vents blowing smoke out of the dash?

If your vents are blowing smoke out of the dash, it could indicate a problem with the heating system, such as coolant leaking onto the engine or exhaust system, creating steam. Another possibility is that the air conditioning system is malfunctioning, leading to condensation buildup. Additionally, electrical issues may cause burning insulation, resulting in smoke. It's important to address this issue immediately, as it could signify a serious problem.
