Once you notice or suspect a damaged blower fan, please make sure to visit the service center immediately to help you fix it. 

Damaged Heater Hose

The heater hose is in charge of transporting heated coolant from and to the heater core. Once it's damaged or has a leakage somewhere, it won't be able to supply the core with sufficient heated coolant, and in turn, the core won't be able to provide the desired warm air inside the car. 

Insufficient Car's Coolant

heating systems work alongside the car's coolants. The heating system won't function properly if there's a shortage of coolant within the system and there won't be sufficient fluid to heat up the heater core. Note that if this isn't fixed on time, it might lead to other issues in your car. It is advisable for you to always check coolant from time to time to ensure it's at its recommended level.
