Cooling Fan Cycling

I know what you are thinking but I am pretty sure it is not going through a regen cycle. I have noticed in the past 3-4 days that my cooling fan runs on high speed for about 30 secs to a 1 min while driving or at idle and it cycles like this frequently. Am I not ever finishing a regen cycle or is there a problem with the fan/something else (2014 JSW)

i see you are in florida. have you been using the ac more as the weather warms up?

It was a warm winter so a.c. has been used most days

Just an update - took it in for service and they found high speed cooling fan inoperative and replaced under CPO warranty
