2011 Ford Explorer xlt blowers keep cutting in and out?

I have a 2011 Ford Explorer xlt and the AC work on it but the blower keep cutting in and out no matter what setting I have the blowers on it I replaced the resistor could it be the motor?

Loose fuse?

No

I would suspect the motor but if you add power and ground to it straight you can check it first instead of guessing. It could be the selector switch also. Or a loose connection. Diagnose it.
