Hi alexiprice,
Thank you for the donation.
Yes, if the fan motor is failing, it would still work intermittently. When carbon brushes are almost worn, the fan motor might stop working and any vibrations can cause the brushes to contact making the motor work again.
Under the glove box, give tha blower fan motor housing some banging with your hands and if the motor starts working, it is time for replacement.
