Air conditioning hissing

Post by Caddy1985 »

Hi,

My air conditioning recently started making a hissing sound coming from behind the centre vents. Now it’s not getting cold and the hissing is louder. I assumed it just needed gas but it’s been checked and is full. I can’t hear the hissing under the bonnet either, just behind the vents. Any suggestions?

Cheers
