The blower motor on my AC will not shut off unless I flip the circuit breaker. I had a condensation leak last week that fried the capacitor, got it replaced but blower will not stop running.

I know this sounds crazy but is the thermostat setting for the blower on automatic and not ON?

In many units there is a blower relay that operates the blower motor in the A/C setting. Many times this relay is on a circuit board also. I would check into that relay as the trouble maker. It might have been damaged by the water or the short circuit causing burning of the contacts inside the relay to shut causing the motor to run all the time.
