Why Is My AC Blowing Smoke in My Car?
There are a few possible reasons for your car AC blowing out smoke. One is the collision between cold, dry air and warm air, which leads to air conditioner condensation. Another possibility is clogged A/C drain holes. Overheating of the air conditioner unit could also be the cause, as well as a malfunctioning motor or compressor. Additionally, a faulty electrical connection may be the reason for the smoke.
Is the smoke coming from the vents when you turn on the AC?
It is highly probable that the white smoke emerging from the cooling system's vents is not actually smoke. In fact, it is more likely to be condensation, particularly if the white fog does not have a noticeable odor. The cooling cycle of the air conditioner involves the intake of warm air, which is subsequently cooled, leading to the production of condensation.
If white smoke is being discharged from the vents of your air conditioner, it is likely to be due to condensation rather than actual smoke. This is especially true if the white fog does not emit any smell. As part of its operation, the air conditioner draws in warm air, which is then cooled, resulting in the accumulation of condensation in the heater box.
If you observe white smoke emanating from your air conditioning vents, it is highly probable that it is not smoke at all. Instead, it is more likely to be condensation, particularly if the white fog does not have a noticeable odor. This occurs as a natural byproduct of the air conditioner's process of cooling warm air.
