Could that mean that there's an issue with the resistor and if you think so, could you explain? I can't comprehend why the resistor could cause the noise with my lack of knowledge with electrical/electronics.VStar650CL wrote: ↑Wed Feb 10, 2021 5:12 amIt's possible there's some stray foam or debris caught in the airway somewhere that's vibrating. That may not be easy to locate. If your blower is a brush type, it's also possible you're hearing HF from the PWM signal to the blower resistor. I personally can't hear it, but I have met customers with very sensitive ears who claimed they could.
No, it would just mean you can hear something most people can't hear, like some folks can hear the tiny buzz from the triac in a ceiling fan but most can't. I'd pull the blower again and the cabin filter as well, give all the seams in the HVAC box that you can reach a careful tactile inspection. If there's anything loose, remove it and see if the noise stops.
Hopefully this loaded. https://youtu.be/TLw2xyh7Mcc
I should've done this yesterday but didn't have the time.VStar650CL wrote: ↑Thu Feb 11, 2021 10:26 amSounds like something whistling inside the HVAC box. I'd still check it for foam protrusions, etc, but if it's deep inside then you may never find it without yanking and disassembling the box.
I'm going to perform both these suggestions today along with getting rid of the somewhat annoying weather alert announcement. I'll try to get pic's and a video of my results and post up later.EdBwoy wrote: ↑Thu Feb 11, 2021 10:30 amYep, I was able to watch your video Joe. It sounds like the car is about to take off.It is not normal, and what I would do to isolate the noise is to take the blower back out and run it while carefully holding it in my hands (still connected to the wire). Run it at varying speeds in different positions - upright, sideways, upside-down, etc
