I have a 2007 pacifica touring edt and I found that I have Water leaking into the rear hatch from the wiper arm where it connects to the wiper arm motor.
Do I have to replace the whole unit or use some sort of caulking to fix issue. It is gathering in the compartment where the jack is stored.

There re could be some water also coming in these 4 holes that connects the rear license plate lighting pulb


Or the leak could b coming in one of these 4 holes
