It works very well now except when the switch is in park there is a leak, wipers park properly but leaks until I move the switch back just slightly. I have had it apart 2 times and cannot see the cause any one run into this before?

It is working well but has a vacuum leak when wipers are in park. | | | | | Joined: Mar 2010 Posts: 10,279 Renaissance Man | | Renaissance Man Joined: Mar 2010 Posts: 10,279 | The switch parts are wear-prone. You are fortunate that you can fiddle with it to make it stop hissing.
