When it stops working try tapping on the blower motor and see if it starts again. I believe it is under the hood passenger side of firewall. If it starts again you need a blower motor

By you tapping the motor it loosens it up briefly. The motor should be new not rebuilt but most parts places you get a year warranty

try tapping the area again, either you have loose wiring or a bad relay. stupid question though, if you could test the power at the motor after, why not before.
