A/C drain tube - Help please
2004 F150 Lariat SuperCab 4x4 (new body style) - I had a lot of water in my front passenger area. I discovered my rear door was leaking bad (found it by spraying water on the rear window and watched water drip out on the inside). I thought that might have been my only problem but since I read about the A/C drain possibly being clogged or otherwise defective, I kept an eye on that too. Today I noticed when after I drive, I can feel a damp spot on a towel I lay up under the passenger side dash, sort of near the center of the truck, but not quite in the center. It's right below the blow box where there's a little foam piece jammed into the blower box, as if that's some sort of drain area.
1. Is this an indication I have the A/C drain tube clogged up problem?
2. Is the drain tube the metal tube that sticks out on the bottom of the truck on the passenger side near one of the small catalytic converters?
3. If it really is clogged, what's the best way to clear it? Can I do it at home? I already blew about 100 lbs of air pressure up that tube and it still drips inside the truck.
4. Is the drip related to a design flaw in the tube and it can't be fixed without replacing the tube with a redesigned factory tube?
Thanks! Please let me know if you have more info on this. I can take pictures of the areas I speak of if you need to see it. But for anyone that's had this problem I'm sure you know what I'm talking about.
