I have a Conquest funace {1994}. When I turn up the thermostat, the exhust fan will come on and then the burners will come on. Next I will hear a "click" but the blower fan won't come on. I replaced the motor and copasiter but to no avail. Any ideas?

Defective relay or fan control depending upon what kind of conntrol system you have.

A wiring diagram is located on the back side of the blower door.
