The wiper mechanisms on 74-78 Imperials and New Yorkers DO NOT pass through the firewall like other Mopar models. This cannot therefore be a point for leaks like it is for some other Mopars. ----- Original Message ----- From: "John Harvey" <50scars@xxxxxxxxxxxx> To: <mailing-list@xxxxxxxxxxxxxxxx> Sent: Monday, November 24, 2003 4:57 PM Subject: Re: IML: water leak I call it the vent plenum. It does let fresh air into the car. It is supposed to have a couple drains, but they do get plugged. However, that isn't your problem. It is remotely possible that the seals where your windshield wiper parts pass through are bad. If so, you are lucky. These are relatively easy to fix, although while you are laying under there trying to do it, you will exercise your vocabulary. I would bet money that your have a rust hole in there somewhere. Try laying on the floor and have someone spary water in there to see where it comes from. You may end up removing a bunch of stuff to be able to pack something up from the under side to fill the hole. It may be at a panel joint, which is a lot like chasing a roof leak. I am pretty sure that you will not be able to reqch it from the top side. John -----
