1990 3.9......I had to work on the wiper mechanism and while doing so broke the plastic T connector on the water line under the grill at the windshield. Anyone know where I can find one? Put it back together just ran straight line to the driver’s side

 

You should be able to find one at a local parts store. I don't know the diameter of the line, but they might even have something small enough at a home imrovement store.

Otherwise, the Chrysler part number is 3671410, and your looking at close to $5 at the dealer.
