Windshield wiper nuts coming loose.

Need a suggestion.

Car does not get driven a lot. It sits in garage a lot. About 20 miles a week on it.

Wiper arms are press fit on to taper on the wiper motor, then held with a nut. Nut keeps coming loose. Is there a torque setting for this, or can I use some blue lock tight on it to keep the nut from coming loose? This is on a 2002 Grand Prix. Both sides are doing this from time to time, and usually at the worse time.

Or is it time to replace the wiper motors. Both wiper arms are less than 2 years old.
Thanks.

Maybe you should watch this video on arm replacement and positioning.
