Versa AC cuts out

It seems like the whole system shuts down. No fan no air almost like a blown fuse but it will work the next time you start the car? Sometimes even after hitting a bump. Basically wondering if anyone else has had this issue. My brother who lives out of state keeps asking me to help him out with it but I can't seem to find any info on common problems. Car has no aftermarket stereo or anything like that so it seems quite odd to me.
