I aM having trouble with my blower fan for Climate control on 2011 Chevy Impala

2011 blower fan was working for heater & AC. Then wouldn't blow until it was on for a few
min. , then would do this sporadically, maybe act up 3-5 times within a week. Then went
to working once a few days, now, the blower does not come on at all for the heater or the
AC, no matter what position we set it as. Sometimes, we would hit under the passenger
side glove compartment, & it would come on, but I just think that was a fluke. I can't tell
how to tell if the fuse is bad, because there's several fuses that read 'fan', & it doesn't
show how to check if bad fuse ( it's different than what I am used to seeing) can you give
me some ideas? Do you know if it would be covered under warranty? I have less than
85,000 miles on it.
