It can be very simple to remove the radiator from a Honda Civic. The first step is to drain the coolant from the radiator. The next step is to disconnect the cooling fan switch and remove the hoses. Then the cooling fan should be removed. Then the radiator should be unbolted and lifted carefully from the vehicle.

Blown fuse. Defective fan motor. Defective thermal relay. Wiring problem.
More than likely the cooling fan is not working. Can be a blown fuse, defective fan motor, or defective temperature sensor relay.
There are a couple of reasons why a Honda Civic heater fan is not working. The fan motor may of blown or a fuse needs to be replaced.
One of the most common (yet often overlooked) problems in the Honda Civic is the radiator fan switch. Another possibility is the radiator fan relay. Not too commonly, the cooling fan motor itself could be bad. Finally, check the wiring and connections to the radiator fan switch and the fan motor to make sure nothing is loose, corroded, or broken.
