I have a 97 deville. Air ride compressor ran and ran and no leveling took place. I would like to know what the hoses are that are attached to the compressor. I know the two little ones from the dryer go to the shocks. There is also a larger one that comes off of the compressor that tees into 2 hoses. One short and one long one. The short one was rotted off and i can not for the life of me figure out where it was supposed to go. i took the tee out and hooked the one long hose back up to the compressor and now everything seems to work okay. What did I unhook?
