Hi all,
If you saw this on another forum I apologize - just trying to be thorough.
I have done my searches regarding this issue of water under the carpet on the Passenger Side of the truck.
My truck: 2006 F150 Lariat 4x4 5.4...
So far I have found:
1. 3rd Brake Light Leak (although mostly stated by 2004) also talks about water in the back seat area and I do not have that.
2. AC Drain - Could be, but I have not been using my AC much, and I noticed this after the rain we just had. Could be coincidence.
3. AC Gasket?
4. Cowell? (whatever that is)
5. Drain plugs in the passenger side floor...
6. Heater Core?

What I want to know is there anyone else who has had this problem, especially anyone with a 2006, and what was it? How'd you fix it?

I have an appointment with the dealership next Tuesday, that is the day their 'Water Specialist' is in, and I want to be as informed as possible before going in.

I've only had this truck for 600 miles - got it last month.
Thanks in advance,
Steve

 

here's another post on this site that was just answered your water is probily coming from th AC. according to one post it does not have to be on very long to collect water here's the link:

The a/c system is used as a dehumidifier when you are running the system in defrost mode. This is to provide warm dry air to aid in clearing the windows quickly. This will cause condensation in the evaporator tray to accumulate, so this could be the source of your water problem. Dan.

 

should it not drain the same way threw the firewall?
