Ac in rear leaking water

Yahoo Message Number: 103419
if it's not one thing, it's another.  Just got back to the coach tonight to big wet spot on bed.  We are in Florida,  so it could of rained.  Opened the rear Ac return.  The electric box marked high voltage is where the water comes out of.  I felt above thinking maybe roof, but seems dry.  There is a T fitting with tubing which appears to be condensation lines.  Which feel dry.  I had the main vent closed so Ac went threw ducts.  Just not sure.  Any advice?

If it rained hard it could've came in through the roof AC. Take off the cover up top and have a look. If drain holes are plugged for the frame of the AC this can force water inside. Also, some AC units have drain pans under the coils. On some models they drain out on the roof on others they are plumbed through to the bottom of the coach. If it didn't rain that hard then I would say that the drain may be plugged. If you don't do this already I would add it to your annual DIY maintenance to clean your AC up top and check/clear your drain lines.
Note: you didn't provide the age of your coach or type please provide this in future emails here lIke min below.

When my roof AC started leaking what I found was that a crack in the plastic shroud that covers the whole rooftop unit was allowing rain water to trickle inside the electrical area of the AC unit and down through a conduit of wires onto the plywood of the ceiling.  I must have hit a low hanging tree branch or something.  Not a huge leak but enough for a periodic drip to leave a wet spot on the floor and a water stain in the ceiling carpet (which came out fine with a professional carpet cleaner).  The only fix needed was a piece of duct tape over the crack in the plastic shroud until I could get a replacement.

We had the exact same thing happen to us.  I removed the cover, put some tape over the crack then filled the crack from the back with epoxy.  Then replaced the cover with a small metal washer-like strip to hold it in place while the epoxy cured.
What was kind of strange was that it was more prone to leak with the coach standing still than when going down the road.
Nevertheless, that was the problem and the repair worked.  I'm trying to avoid replacing the covers unless really necessary since they are painted to match the coach's color scheme.

Yeah, looks just like mine. The hoses are coming from your drain pan and should exit out the bottom of the coach. Did you do any troubleshooting up top? Remove the cover etc.. When I lived in Florida my coils/pan would get gunk (alge I guess). It would plug the drain holes and the water(condensation) for the AC and would overflow through that big opening in your picture. You can go on YouTube and they have some videos on how to clean the AC, pan and drain lines. Also a really hard side rain can get in your AC vents on the metal casing of the AC and build up in the bottom especially if their are no drain holes in the casing. This will cause the same leak especially if you are not level. Alex Ritchey 2000 affinity 42' tag B&B alexritchey65@...
