I have an 04' F-150 5.4, When I run the ac and then shut the truck off I notice water on the floor board. I believe the drain hole may be clogged. Has anyone ever had this problem, if so is it an east fix? Any help is appreciated. Thanks!

 

hmmm...I have the same problem with my 04 heritage and am looking for answers. Did you ever fix this?? I traced it down to somewhere in the A/C system and think, like you, it has something to do with the drain.

 

Crawl under the passenger side of your truck and look for the rubber drain extending from the firewall. Squeeze the end to make sure it id not stuck shut. If it is, the water should drain when you squeeze it. If this doesn't work, you may have to carefully stick something into the drain.
