Holding water in the front back and trunk how do i get rid of the water in my 1998 plymouth neon

If I'm reading your complaint correctly,the real problem is "how is the water getting there in the first place"?Start by inspecting the weather stripping around the doors and trunk for splits/cracks/missing sections and replace as neccesary.Most vehicles have drain plugs in the floors.accessing them will require pulling up the carpet.Good luck.
