I had the same problem. The wiring got hot and one connection would intermittently work. I had the pigtail replaced and spliced in. No problem since. Replacing the motor probably won’t work if it is the same thing

Most likely the BCM is bad. Try tapping it with a screw driver.

99.9% chance it's BCM.

Mine did same, 2 times W/I a 90 day period.

The 2nd has been going good for 4 or 5 years now.

Get Motorcraft replacement, the aftermarket ones are junk.
