Another photo from the interior. Cyan circle. Planning on using this locator to approach the issue in the Spring-time.

 

Remember, the other side of the firewall appears differently, as that duckbill hole is in an enclosed area, and you access the duckbill from a hole below it. See the line drawing in post #7 in this thread:

It wouldn’t take a rocket scientist to conclude that the duckbill would clog over time. I do appreciate the effort to keep bugs out…but really how’d they think that would weep water consistently over time?BTW…do all XK model years have this issue? Or did they correct it in the later years?

Does the attached photo accurately represent the design used in 2010+ models? Does this solve the problem? Are there other issues with bugs crawling up into the ac on these?\

 

Hmmm, an idea just hit me, wish I’d thought of it while I still had an intact duckbill (although slicing it off was probably a better solution anyway).
Find something hollow and flat enough to fit between the transmission housing and firewall, with a hole to match up over the duckbill hole, add some foam weather strip around the hole, slide it in to cover the hole, and connect a shop vac to an open end on this doohickey, and suck air though the duckbill to clear it out. Eh, just a thought.

 

Drill a small hole in the bottom center area of heater box, shove a Borescope Camera through the hole and maneuver it to the duckie and push it through. Withdraw the scope and speedtape the hole. DONE.
