Volkswagen Tiguan manual gear heater adjustment is broken, what should I do?
if the car heating system is not used for a long time, the warm air may not be hot when it is used in winter. The main reason is that the small warm air tank is blocked. After the small warm air tank is blocked, hot water does not pass through the small warm air tank, which may lead to cold air blowing out. This phenomenon is caused by the owner's long-term failure to replace antifreeze. If the air-conditioning pipes are not cleaned for a long time, the small water tank of warm air will be blocked easily. It is suggested that the owner should make a comprehensive maintenance of the warm air system of the car before winter comes.
the damage of the heater control panel is just like the bulb control switch at home. When the owner turns on the heater switch, the heater switch fails to transmit the corresponding heater supply signal, resulting in the phenomenon that the heater is not hot. If the heater switch causes the heater to be not hot, the owner needs to go to a professional repair shop or a 4s shop for treatment.
There is air in the waterway, which leads to insufficient hot air supply and abnormal warm air. The air in the waterway will not only keep the warm air warm, but also lead to other faults caused by the high temperature of the engine in serious cases, which requires the owner to deal with it in time. If he can't handle it himself, it is recommended to find professional maintenance personnel to deal with it.
