Lets disconnect wires fron thermostat to air handler to pinpoint issue to the air handler first

What I am trying to do is determine if issue lies inside the air handler or has any outside issue. If we take thermostat wires loose at air handler and blower still runs we will concentrate completely on the air handler.If disconnecting thermostat wires at air handler causes blower to stop we will concentrate on thermostat.
