Why is my heater running but no heat?

Will a blown fuse cause my heater not to work?
If you think the cause for your car heating not working is related to the blower fuse, be sure to replace it with one of the same amperage. The fuse may have blown due to age, or it may suggest an underlying problem. If the replacement fuse (of the same amperage) does not blow, you may well have identified the problem.
What to check if heat is not working in car?
The first thing to do if you’re having issues with your car heater is to check your engine coolant. Make sure to do this when your engine has cooled down to avoid being burned. If your coolant level is too low, there won’t be enough hot liquid in the heater core, resulting in cold air.
To clean the blockage, you need to flush water or air through the heater core. By doing so, the grime and dirt that’s causing the clog will come out through the inlet hose. Now, insert a water hose into the outlet hose. If you have access to an air compressor, you can use that to push out the coolant and grime.
