05 Cmax Air Con Problem

[Bartman]

Hello,

New member here and Help needed !! I have a 05 plate Cmax Titanium 2L tdci and the air conditioning has stopped working properly, it starts up ok and gives out cold air from vents, then a hissing noise can be heard in the car, then the temp out of the vents drops, then I can hear the air con compressor switching in and out at about one minute intervals. Has any member had this experiance.

Any help/advice would be great.

Thanks Steve
