I have a 2016 Edge Titanium AWD with the 3.5L engine. The car has 23,000 miles. There is a sound (like shaking marbles) that seems to be coming from the A/C system. There is no sound in the cabin, just when you stand outside the passenger side. The pitch changes when the A/C cycles on/off. Does anyone have an idea what his might be? My mechanic cannot seem to sort it out.
I searched high and low trying to find a thread on the forum that deals with this, but to no avail. If one escaped me, please let me know.
