Heater blower motor is defective and locked up, or possible short in the wiring.
for fuse to keep blowing, there is a short in the eletrical system somewhere. check the a/c switch and the a/c clutch
Sounds like it could be the ECM fuse. You need to have someone check it for a short.
i replaced the head unit and the fuse stoped blowing.
faulty control valve on heater or air in the lines
Low coolant and a clogged heater core are possibilities.
You need to change your thermostat in the car.
No...
The heater core is leaking coolant.
sounds like an electrical short. go to an auto electric shop for a proper diagnosis.
A car heater may stop blowing due to several reasons, including a malfunctioning blower motor, a blown fuse, or a clogged cabin air filter. It could also be caused by low coolant levels or a leak in the heating system, which prevents proper heat circulation. Additionally, issues with the thermostat or heater core can impact heating performance. Regular maintenance can help prevent these problems.
it is your heater core most likey
maybe because the heat is to high for the fuse to bear. You probably have it on all the time If it blows as soon as you turn it on, it is a dead short, pinched wire, bad blower motor. If it takes a while for it to blow, it is probably the blower motor going bad causing a strain and drawing more current than intended.
