Default Blower Fan Cutting In & Out

I'm on the 3rd blower fan and power control module. They both usually only last a year. I know when fan is ready to go because it starts to shut off and on automatically until it stops all together. Had a GM mechanic (20+ years) look at my car for shorts, grounds, etc. and other issues and found nothing. He is baffled as to what this could be. He said maybe computer.

I've had other weird electrical things like cruise control working and not working. Low coolant light coming on and off. Engine running rough and then working it'* way out of it. etc.

Anyone have any ideas?
