Aftermarket window leak

My van came with aftermarket windows behind driver and passenger side, the drivers side seems to have water gathering at the back of it, I park on the drive at a slant and noticed quite a lot of water at the rear of the window towards the rear, at first I thought it could be condensation but there hell of a lot and zero on the passenger side rear window, it rained again last night so I can only assume it’s that, I know about drain holes and can see the front one where the window slides open, any ideas how to access the rear one, or could it be something else?

I remember our old T5 had a roof rack fitted at some point but removed when we got the van, and the mounting holes/bungs in the roof were missing the rubber seals and they leaked water into the van, so check there maybe.

If no joy, get someone to run a hose pipe around the window from the outside while you are inside to check it is indeed the window that leaks.
Only real fix it is to have it removed and have a reputable window installed by a pro.
 
I think I may have solved it, there is some rubber sealant at the end of the window, looks like this one just doesn’t have enough so there’s a slight hole in there allowing water to seep down on an incline. All the weep holes are free so it’s not them, anyway I’ve filled it with extra sealant and fingers crossed that works.
