2007 Crescendo Water leaks

[Vickie 4369]

I have been chasing a water leak and hope that someone may have a lead for me.
So Far I have resealed the Front Seam Left to right,
Both CB antennas
Roof mounted Crank up antenna
Fantastic roof vent

All by complete removal cleaning and resealing with Dicor products.

The Water drips from the Vinyl covered panel close to but above the windshield

And the Pass side front Carpet gets soaked every time it rains, Maybe Side Window??.

I also went over all the sealer around the other items further back.

I have not touched the Front AC yet because I ordered Seal kits before I remove them and I don't have them yet.

Any advice is appreciated.

Ted.

Have you sealed the clearance lights? That fixed my water leak.

Yes I forgot to mention that.

We're having a similar problem. Done everything except one last stab at it with a pressure test. Same location by the driver's left foot and also coming out of a square channel that runs on the left wall above the driver. I found this one by removing the top piece of pillar molding. Next is Lazy Days in Florida for a pressure test where they pump a lot of air inside and look for it coming out using soapy water. That should do it. I'm glad we replaced the carpet with laminate wood flooring which is when we discovered mold and mildew which required mold remediation.

My next stab is to pull the air conditioners and replace the gaskets.

Then I will do the same, Hemlock Hill RV has the same machine and offered to do that test as a last resort.

Update; The ac gaskets are perfect, the bolts took a few turns but I don't feel there is any leaks here.

I will find it some day.

Are you sure it's a leak and not condensation buildup.
On my 2006 I had condensation running down the front window.
After removing the face to the front cabinets I found that the insulation which was supposed to be attached to the front cap above the windshield was just handing. I tried to reattach it but it wouldn't stay.
What I did was get some spray foam. Not the cans you find in Lower or HD
But actual spray foam. That took care of the problem.
Just do a search for spray foam you can find small self contained units.

Thank you for the tip but it only leaks when it rains.

I keep a vent open and either the heat or AC on to keep things dry.
