Alright so... The best way I can describe this as follows: If you take the AUX cord in a car, plug one end into the radio and then touch the other end to something metal as to ground it you'll hear what I describe as the electronic sound of the injectors. Like a these high pitched electric clicks that speeds up with engine speed. We used to do this in the honda in high school because it sounded kind of cool.
Anyway...
So... my blower motor in the truck is now
emitting this sound... As if it was a speaker... What? If I turn off the blower, the sounds stop instantly, and if i turn it on the sounds come back. Note that this is with the radio on or off and I've made no modifications. It's definitely that "electric injector" sound as it follows the enigne speed perfectly.
Is the blower motor...somehow acting like a speaker? Is that even possible? What even. Should I replace it? Or...do I need to grease it?
Not sure if it matters, but 2000 SR5 V6 Auto.
