May want to pull the blower assembly out to make sure nothing has come apart in there....or a rock, twig or something may have entered in there and is interferring... good luck!
I cleaned the filter, wasn't very dirty. Checked the fuse and spun the blower wheel by hand. Started the car and came back on. Pretty confusing, but I ordered a new blower fan just in case it goes out again and I expect it will. Thanks for all your support. I'll keep you informed if I need to change the motor.
