BUMP
I had thought I posted this, but I guess not; at least not that I could find. I was just going through some stuff again and thought this might interest some people. Check out TSB 23-008-03 from 4/11/03.

SUBJECT: Right Side Cowl Water Leak
OVERVIEW: This bulletin involves sealing a right side cowl seam.
MODELS: 2003 PL Neon/SX 2.0
SYMPTOM/CONDITION: Water on the right front passenger floor.
DIAGNOSIS: Run water over the right lower A-pillar with a garden hose. Remove passenger side cowl trim and pull back floor carpet to confirm water leaking into passenger compartment. If water/leak is present, perform the repair procedure.
REPAIR PROCEDURE:
1. Open Hood.
2. Remove the three screws holding the cowl grille/screen on the passenger side of the vehicle.
3. Partially remove hood to cowl seal, at the leading edge of cowl grille/screen.
4. Disengage grille/cowl screen anchor at center of cowl.

The sealer beads are at the junction of the A-pillar, cowl plenum upper and cowl side panel. Apply Mopar Silicone Windshield & Glass Sealer, p/n 04467708, to the outer edge of all existing sealer beads.
7. Allow sealer to set up for 30 minutes. Water test right lower cowl area to verify repair. install passenger side cowl trim.

-Thanks for this, and what timing! I'll be doing this to my Wife's '05 Neon tomorrow morning. She's had quite a bit of water leaking form the last couple heavy downpours we had. Picked myself up a tube of 50 year, silicone sealer the other day. I thought it was from the fresh air intake being so close to the cowl plenum. I checked it out a couple weeks ago because I thought maybe the fender drains were plugged and water backed up to the intake. But everything was clean as a whistle. So I bought the sealer to go over the factory beads just to make sure. Now I know EXACTLY where to put it. Thanks again.
I am from finland and i have this 2nd Neon 2001 and i HAVE excatly same problem with you guys!
It started when i changed my windshield this summer, i`ve been having this problem like 3 months now... Water has come like 3-6 times inside car from under dash passenger side......
