Noticed my fan started making noise when it starts up. Thought there was somehting caught in between but nothing was found. When the fan is spun by hand, I can hear the sound as the fan spins. So, I concluded that the bearing maybe on the way out. I was wondering if anyone here has the 'blower/fan unit' for sale. Thank you guys ... Oh, I'm assuming the fan unit would be a 'universal' fit over the range of models. Just in case, mine is a 2018 S10ES.
