Is water dripping from the car AC normal?
Water dripping from an air conditioner is usually normal condensation functioning as intended, but it can sometimes indicate an issue depending on where it originates or if it follows an impact like hitting a road hazard. Knowing whether it is standard condensation or a leak prevents unnecessary anxiety and helps determine if a drain plug needs attention.
