Default Re: MB air conditioner blockage?

Hi all,
I ended up getting the fan replaced which seems to have rectified the cooling issue finally.
What I have now noticed though is that when the air conditioner is on it makes a slow pulsing hissing sound. It’s quite loud unless I have the radio on and I’ve never noticed this before.
I’m on AL at the moment so will take back to auto electrician when I return but does anyone know what could be causing this?

By slow pulsing hissing I mean it hisses for a couple of seconds then fades out to nothing then fades back to hissing and it’s constantly doing this while the air is on.
