There is indeed a hissing, but im not sure if it is the hose in my trunk with a leak. I feel it might be the actual locking mechanism under the trunk door lining itself- when i press lock/unlock, it almost gets there and sometimes does. Otherwise, the little bar that moves that comes out of the big piece under it (nice description right?) will lock and unlock if i give it the slightest push to help it... I tried oiling it but no use-

I guess it could still be a leak in the hose and the suction power is just not enough, but I can't seem to find the hose- in the trunk door or on the side of the trunk- does it run through the pass side im guessing? color? thickness?

thanksss
