Just to jump in on this because this could be a couple things including the motor still.
Basically, when it comes on when it wants to, what is happening is there is a short in the circuit and when this is open the blower will not work. When it is not, the blower will work normally.
This is normally not a fuse but a contact in the circuit somewhere which is a relay, resistor, or even the motor.
So, the way we need to check this is when this is acting up again, we need to check for power at the blower and find out if it is there.

I am attaching the wiring diagram below. If you don't have voltage at the motor, then we need to go to the control module which is a resistor and check for voltage there on each wire with the engine on and blower turned on.
Please let us know what questions you have on this.
Thanks
