2019 Anthem roof leak
 
Has anyone had an issue with water leaking in at the drivers side window from above the roller shades ? I have checked the caulking at the seams on the cap and checked the gutters (all good) but in a heavy rain there is water leaking in over the d/s blinds.

I had a bad leak on my 15 Anthem that was due to the Girard awning feet and anchoring screws pulling out of the fiberglass/wood roof. My coach was waterproof for about a year and ~ 12,000 miles and then developed a real big leak that was the exact opposite side as yours..... above the entrance door. I discovered that it was soaking all the insulation between the wall studs the whole way back behind the passenger seat (took of the light switch panels and everything was soaked inside the walls) and around the front of the coach to the first speaker mounted above the windshield.

To Entegra's credit, they diagnosed this as a much bigger problem than I did and asked me if I could detour to the factory which I did and the coach was in the shop for about 10 days, in their heavy rain simulator twice while they tore out the cabinets and the sheetrock around the door and the compartment above the door. They replaced the fiberglass insulation, the sheetrock and found the problem. The problem they were worried about most was mold buildup behind the sheet rock and cabinets and wanted to make sure that was perfectly dry before letting me go.

The problem was produced by the Girard mounting feet screws that had probably been overtightened when installed and the threads of the screws either pulled out right when they were installed, or vibration as the coach traveled made the front screws pull out or get loose and those holes then became the path for water to enter. My understanding was that you could not see the holes because the awning still appeared to be mounted solidly but that the bracket covered the problem. I dont know exactly what they did to solve the leak but assumed they used much larger screws to hold down the "foot" and then water sealed the whole issue. Problem never came back.

Of course, that is just one possibility in that general area (I think your coach has the "fake" awnings on the driver side so it could be the same issue).

Edit: the most common leak source over the years from 2014 to 2017 or so is a leak in the clearance lights on the front cap produced by a bad seal in mounting the lights (which usually are simply potted into the indentation with sealant. Sometimes the lenses crack and admit water and more often the seal develops a crack.... the usual diagnostic sign of this is that the water leaks down from one of the mounted speakers above the windshield).

I had that same issue recently when i was in Seattle area it rained heavy for 5 days , then i notice a leak in the same area you mention , for a temp i tilted the MH to the right then the the passenger side leaked as well same place.so then i raised the front end till i could get outside and look.. The front cap area right where the gutter needed some sealing, it looked sealed but there was some hairline cracked that the caulk was letting in water both sides had this issue. It was too wet to put on caulk so temp fix i used flex seal tape and that worked, next week i am going to work on resealing those areas and the roof with eternabond...

Jack,
I had a leak in the same spot and condition. NIRVC Lewisville did a bubble test and found the sealant that looked good was actually leaking. They resealed it and all is dry now.

Peal back the plastic cover piece that joins the sidewall to the roof and transitions forward to the front cap and look for missing or broken screws and replace and caulk those areas. This was a problem from years ago where holes were drilled for the transition piece but no screws were put in or broke and allowed water into the chase for the wires and the exit point inside was above the drivers side window.

I found this on my new 2020 Reatta XL , inspecting the front cap amber lights I notice the lenses were cracked and fell off when I touched them. The rubber mount that holds the clearance light had somehow become solid and could leak. I covered them all with orange hd tape. The dealer will install new ones this week which I hope will fair better. The rubber was so hard it will have to be cut out.
