We have a class c that the passenger rear and dining side window seems to be leaking.We are unable to find out how the water is getting in.Any suggestions?

I have had windows leak around the seal, I used a clear silicone caulk and it never leaked again.
Also make sure the drain holes are not clogged and backing up to the inside.

remeber that where the water shows up is not necessarily where the water entered, it can travel a long way before it finds an exit. If both windows are close to each other I would suspect a common entrance point IE roof, vent etc. Start by using a water hose at the bottom of the window and have a helper inside to check for leaks. Slowly move the hose higher and higher up the window to see when it leaks, if not try various places on the roof until leak pinpointed. Pay attention to clearance lights, a problem on my class c. Also make sure the A/C is snug on the roof, mine loosened off the hold down bolts and let water in there. Seam between roof and end caps also problematic, used Eternabond tape on them no leaks now. Good luck

I had a leaking window and found they had joined the metal frame at the bottom and water would run along the joint to the inside.
I also have horizontal corrugated siding and water would run from a leak at the front corner to the window. Window leakes are realy hard to fix.
Have you tried the process of pressurizing the
rv and putting soap mixture on the seames to find out were the leak is?
Most RV repair shops should be able to do this.
Good luck.

If your windows have screws on the inside to connect the two frames togeather try tighting them.

Make sure you get this fixed. I have been looking at used motorhomes and found a lot of delamination usually below windows that have been leaking.

best way to find your window leak is to have someone in side unit while holding a garden hose turned on pointing at bottom of window then moving it from side to side and up ontil the window starts leaking inside
