What is your question?
this happens only some time but more frequently lately,seems to be in the control circuitry, could be a relay or resistor failing .

Most likely a bad relay would cause the fan not to work at all, not just sometimes. Sounds like it could be a wiring problem or a problem in the HVAC control unit.
I ran into that twice.....pigtail melts on the end....wonder why??
High resistance caused by poor connection creates heat... NAPA..... GM offers a repair kit with resistor and wire/connector.
