Water Leak

[Anthonytony]

I have had my neon for a couple weeks now and blackroseracing (my dad) suggested me to join this site for more info on my car. Just have one problem that I don’t know how to fix. I have water leaking on the front passenger floor board what looks like to be from the firewall. Does anyone have any idea what is cause this? We have check the sunroof drain and it seems to be intact. Idk what else it is.

Mine does the same thing and I don't even have a sunroof. I suspect there are drain passages under the cowl that need to be cleared of debris, because that's where it comes in.

Kudos to Chris (BRR) for not spoon feeding!

There is also a caulk joint issue that lets water in under the cowl. Apparently some cars didn't get caulked well enough ... But definitely pull the wipers and cowl screen and clean out both sides of debris, if it is full.

Also check the front door gaskets. While not a common issue, it does happen. I had to replace the passenger one on my '01, because water would cross over past the seal on the "A" pillar, and run inside the car. No matter what I tried, it would not stop. After replacing the door gasket, it stayed dry inside.

There was no damage to either the gasket or "A" pillar surface, but for whatever reason, the water would go right between it.

Of course there is the HVAC drain, but unless it was also happening on sunny humid days, that probably isn't your issue.

The top of the heater box above the blower motor is wet. I walked him through making sure the sunroof drain tube was clear and not disconnected.
I read last night about the sheet metal area with cracked sealer but I don’t believe it could be that because of the amount of water on his floor.
Last night I ordered a “Flir One” thermal camera and I’ll try to use that to trace the water.
I’m actually thinking the windshield might be leaking

Thank you so much. That’s what my dad is under the assumption that it is a windshield leak.

I used a Thermal Camera today and he has heat escaping out of the passenger side under the windshield in about a 3"-4" area. I'm going to guess this is where the water is actually coming into the car since heat can escape through there, it's large enough for water to come in

Any update, OP? Did you find the source of the leak?

[BlackRoseRacing]

No real updates yet as my kid has yet to listen to me and get the windshield resealed. So as of now he's still getting water inside the car and with the WNY temperatures lately, I'm sure it's freezing water now.
I've told him numerous times it needs to be addressed as it could lead to further issues, but of course he's independent and won't listen to what he's being told so he has not taken the step to get the windshield resealed to see if that fixes the problem. So I'm guessing he is going to run into further issues sooner or later since he has not tried this repair yet.
