Yesterday, I noticed a sort of ' gurgling' noise coming from the passenger side. Its a very subtle noise, a cross between the gurgling and a flapping sound.

I eliminated the stereo, so can only think its coming from the vent that blows to the passenger window. Is it possible for something to get in there?

Any other suggestions as to what else out could be?

I had that, it maybe a leaf in the fan motor, pull the side cover off the dashboard and you can see in.

I had this, took the car back to the Dealer and it needs a new air con compressor. Luckily a warranty job. Of course I couldn't be 100% sure that yours is the same, does it still blow cold air? Hard to tell in this recent cold spell I know
