AC noise after shutting car off

I searched and could not really find an answer to my problem.


2008 C230. AC is a bit noisy after shutting the car off. AC will make a ticking/gurgling sound for a minute or so then quiet down. Like fluid or something is draining and with a weird clicking or ticking noise.


Any ideas what this might be?


AC works fine with no issues other than the short burst of noise.

I've heard this too. I've also heard this when the car is in a hot place hours after it has shut off. I don't know what it is.

No, it sounds like a fan in my case.

Found out what the noise is.


My hood release cable came out of the retaining clip portion of my grill support so when I'd shut the car off, the cable would drag a bit on the fan while it stopped spinning and was giving me the ticking sound.
