Gurgling bubbling sounds from my 85D

Refrigerant most likely. AC compressor pressurizes the gas into a liquid which evaporates back into a gas in the evaporator. When doing short runs (common in "nice" weather) it may not run long enough to get everything fully running and you may hear some gurgling sounds.

Turn the temperature down to a very low temp and see if the gurgling goes away after two-three minutes. If so, it should be ok.

If its the one I hear, it sounds like coolant not refrigerant. Previously I had a a Durango that would blow out heater cores on a regular basis, every time it happened I would hear very similar sounds.

There is no coolant in the dash, only AC refrigerant which doesn't make that noise. The heater is a PTC air heater.

The coolant reservoir is just on the other side of the firewall though, and gurgling could mean there are bubbles in the coolant. Tesla has a vacuum device to bleed the system and remove all bubbles. If you are hearing gurgling, next time your car is in for service, have them vacuum bleed it.

It's actually a zen like experience.
Relax your mind as you listen to the calming sound of the gurgling forest stream, brought to you by the good folks at Tesla Motors.
I'm sure it's not harming anything. It's just a different noise and I wondered if I really heard it or if I was obtaining the skill of the zen master.
