Where is it? Where does it come out?

Over the winter and early spring there wasn't any reason to notice the hvac puddle under the truck. Since the rains started, I thought I developed a leak, since my drivers side carpet is wet.

Turns out, I had a brain fart. I remembered my Expedition did the same thing. The hvac drain was plugged, and overflowing into the cab. What confirms it for my F150 is there was no hvac puddle today after running the a/c. And the leak that isn't, in the winter and early spring, was the hvac on defrost, which also uses a/c.

So, does anybody know where the drain is supposed to be? Because I checked today with a hot exhaust and I couldn't find it.

 

Gotta pull the liner? That's just wonderful.

 

Got a part number for that elbow?

 

Thanks Ken.

I went to the dealer today, said they could get it for tomorrow, $32.

I think I'll try eBay or Amazon.

I'm heading out tomorrow afternoon, so I can't exactly wait, gonna just use a pipe cleaner on the drain.

 

Good thing I didn't order the elbow, because the drain wasn't plugged.

Still baffled by the fact that there isn't any condensation coming out of it though.

As to the wet floor, I pulled up the carpet and found the TOP of the duct to the rear seat heat was wet with condensation. I'm wondering if there's some crap from the kids jammed in the outlet, or if this is a common issue or design flaw with these trucks.

Off to the search engine, will keep you posted.

 

Some of what I read last night said it was still the hvac drain, and that I should get the elbow, and others said it was leaking from the third brake light, filling up the wiring trough and making its way forward to the drivers floor.

Ordered a smoked led third brake light. Hope it comes with a gasket.

Gonna go back to the Ford dealer on Monday and order the elbow.

Covering 2 bases that way.
