What should I do if the warm air is too bad in Geely Panda 1.3?

poor warm air is generally caused by the blockage and poor circulation of the warm air tank. It's best not to add water to the car. Always use antifreeze. If there is water leakage, repair it in time. Don't add water if there is less antifreeze. There will be scale in the waterway for a long time. Take apart the warm air hose and check it. If it really doesn't work, replace the warm air tank. I hope it will help you, please adopt it.
