Heater Blower, Accord

Heater Blower not working. 93 accord, I replaced the blower motor and the 30A fuse in the engine compartment. On the AC/heater control panel all buttons seems to work except the actual heater switch. No air comes out of the vents. I can hear the switch clicking through all sets 1-5, but I hear no power or fan action nor feel any air.
Please, does any one have any suggestions.

In the blower motor control circuit between the 30a fuse and the motor is a blower motor relay. What causes it to activate is voltage through a 7.5amp fuse (I think fuse no. 8). On the other side of the motor is the fan speed switch which is a group of resistors selected depending on the speed selected. At the fast speed, the motor lead goes to ground. Fuse no. 8 also controls the radiator fan relay, rear window defogger circuit and the anti-lock brake control circuit and cooling fan timer unit. So if they don't work, look to fuse no. 8.
