Hyundai Sonata dashboard clicking noise leads to malfunction of windshield wipers, AC/heat controls, and sunroof on Hyundai Sonata

Some Hyundai Sonata owners report experiencing a clicking noise from the dashboard that may affect the windshield wipers, AC/heat controls, and sunroof. This noise can be attributed to various causes, including the heater control module losing calibration, a faulty blend door stepper motor, or a relay issue. Additionally, some owners find that the clicking may result from the gear movement of the internal air diversion flap within the air pipe, especially when cabin humidity increases and the system activates the Aircon to direct cool air toward the windscreen. It is recommended that owners experiencing these issues seek diagnosis from a qualified mechanic or technician to effectively resolve the problem.
