Whenever the engine is running behind the middle part of the dash it sounds like the air conditioner is going but that doesnt even work, does anybody know what could be making this sound?

sounds like it !

yeah like a hissing sound.. couldnt be the headunit cause it was doing this before i installed a headunit
theres a few lines behind the fan control, might have to take apart the dash to get to it and fix it the right way, you dont wanna pull on the lines and pull something else and end up with another prolbem. by a gregs or max manual book bro heaps of info only cost you 40 dollars!!

there is only one vac line coming in from engine bay to rear of the control for the air flow.
The others go off to control air to feet/face/demister etc either its the feed of come off round disk with all other vac lines
not a hard prob at all one screw where fan control is and your got it.
Watch the heater box control rods
