The three little plastic nipples (attached to yellow lines are all supposed to emit air when locking correct?? I took the housing that holds the 2 lines off and hit the lock function on the key fob. Only one of the nipples emits air. I don't think I have a vacuum leak anywhere ...I really think it's a bad pump, but before I shell out $400 for a new pump I would like to be able to test the one in my car. I've checked fuse #9 in the fuse box...it's good. Any help bench testing this unit would be appreciated. vr, Lee
Did it just fail all at once or is it a problem that that has got progressively worse?
The lines can get brittle and break the most common is the hatch lock on coupes.
You say you took the housing off that holds two lines, do you mean the manifold with three lines? I am sure that it is fed underneath by one port for air and one vacuum port.
If you took of the three hoses from the manifold each one would blow or suck. Only by doing this would you know that they at least were working. In which case you probably have broken air lines somewhere.
Here is some pictures.
