Leaking AC vent.

[Nicholsfamily05]

So I have been using my 5er fas a place to sleep for the past few months while we have some major overtime at work. Saves me the 45 minute drive home after working 16-18 hrs. On Sunday I came home to it and the master bed was soaked.
Went searching around and located the place where water got in. It came in through the AC vent right above the bed.
I checked the roof and it appears everything ok up there but short of pulling off the whole AC I couldn't see anything. I did take the top of the shroud off but it didn't help.
So I cleaned it all out with my air hose but nothing came out as of dirt or debris.
Now we had another rain storm during the night and woke up to water steadily dropping on me. Put a pan there just to collect it but called dealer and they said drop off next week. Guess they don't realize " hey it's raining in my brand new trailer."

Anyone have some ideas to fix it without waiting. I don't have a tarp to cover it. I may just go buy a RV cover.

It's a 2017 Sierra 377FLIK (front living room). No other leaks anywhere else'.

Tried loading photos but photo bucket isn't working

I didn't get a very good picture of the whole room but here is the bedroom.
I can only access the ac from the room but I imagine it's the same with the bolts.
Heading to it once my kids are on the bus this morning.
Crappy part is it's already raining and by the time I get to it the weather says it will be raining buckets.

Yay



It's the rear AC

Been there. Remove the inside AC cover and look for 4 long bolts like this. Yours may look different but they are all about the same.



Give each bolt one 360 degree turn right to tighten. Look at the gray gasket if you can see it (mine was gray) as you tighten to see if you can detect the gasket compressing. If you do not feel any resistance tighten them a little more but do not over tighten. If you can physically see the gasket compressing do not tighten any more.

Wait for rain or use a water hose to wet well around the roof AC unit. If it still leaks turn them 360 degrees again. If this again fails replace your seal.

Mine failed after 6 years and I had to replace the seal. Easy two person job.

On my brand new Montana, the front mounting bolts where stripped out. Had to remove ac unit, clean roof, vacuum out debris in return air ducts from factory, drill new holes in metal cross bar for new screws would catch a beam in the ceiling. All is good now.

My Keystone built fiver must have been built on hangover Monday with all we have found wrong. The stealership was in no rush to help either.

My unit is going back in for the third time to fix the fridge.

I had this issue myself and when I called the dealer to set an appointment to take it in they said sure bring it in but if you want to, its an easy fix you can do yourself. Apparently, the front A/C gets installed at the factory and the 4 bolts that hold it down loosen somewhat during the initial delivery travel to your dealer. I climbed on the roof, pulled the shroud, tightened the 4 bolts a turn or two and its never leaked since.

Hm. Guess I'll try those options before dragging it back to the dealer. Would be a lot easier.
And thanks for the link as well.

This is the likely issue. Take note... inch lbs!! I would just check to see that the 4 bolts are snugged about the same. The gasket should not be crushed tightly.

AC cover just stops rain from entering the AC.
If the leak is between the AC gasket and the roof its still going to leak.

Try a cover but keep a bucket handy.

Use the picture upload app referenced in the Tech support section. It works very well.
