Hey all I noticed one day a hissing coming from the vents (or I thought) and was bugging out long story short I drive to my mechanics and bam it stops! So I was like hmm guess it was nothing.. Today I start my car and hear it again but this time I heard it louder and put my ear to the climate control and took the dash off etc and it was where you change the dash, floor, defrost settings I took it apart and nothing seems to work there's not many parts any ideas? Please help it's driving me nuts and it's not all the time also I think I need to change the climate control but want to make sure before I spend the cash thanks!
