BYD DOLPHIN windscreen fogging in damp weather

Symptoms

  • The windscreen fogs up in damp weather. [1]

Possible causes

  • Cold air directed at the windscreen creates an inside/outside temperature difference; continuing to use recirculation after warming up the vehicle also works against fog prevention. [1]

Checks

  • Check airflow and recirculation settings, and confirm that the air intake grille in front of the windscreen is not blocked by leaves or snow. [1]

What to do

  • Avoid directing cold air at the windscreen in damp weather; use fresh-air mode after warming up the vehicle. In cold conditions, run the fan at high speed for one minute to clear snow or moisture from the intake duct. [1]

Applicability and limits

  • New Zealand DOLPHIN, 2023-09 manual edition; the manual date is not a model year, and dictionary mapping has not been established. Scope: unknown [1]
