In the last couple weeks I have noticed a hissing sound when my air conditiioning is on. It comes and goes the hissing noise. It doesn't matter if its on max a/c or normal a/c. So i'm wondering if i have a leak or something. Anyone have any ideas before i bring it in.

My truck does the same thing, always has . Not sure what it is but I just took it for granted that it was normal as my AC has always worked very well.

Do you have the heated and cooled seats? If so and you have the cooling on the fan makes quite a bit of noise, took me about a day to figure it out not sure if it is the same problem you are having or not
