hey guys! I have a 2017 F150 3.5 ecoboost FX4 with a 10 speed transmission. After I turn off my engine, there is a high pitched whistling sound on the passenger side. I took it to the dealership, but they can’t seem to figure out what it is. I’ll post a video so you can hear for yourself. From what I can tell, it’s not hindering anything in my truck, just curious to see if anyone might know what it could be making that sound. Has anyone dealt with this? Thanks guys!!
