At my last service appointment for a charge port door issue, when I was at the SC to picked up my car, and as I opened the door to get into driver seat, I noticed the A/C fan was on full blast - since it was a hot day, the technician may have turned it up to high as he was moving the car to the pickup spot in the parking lot. The problem was not with the A/C being on full blast, but I started to hear gurgling noise coming from the front. I've attached a quick video of the gurgling noise. I don't recall hearing this sound at all for the past summers using the A/C. Is this a precursor to a malfunctioning A/C? You can hear that part of the sound is the air intake actuator probably closing after a drive. But the gurgling has me concerned.
