Hope everyone is doing well and enjoying this gorgeous weather!! We've just taken our tourer out for the first time and unfortunately in one front window there is a lot of condensation and water pooling at the bottom 🫣 Any ideas how to fix this???
Ah. We had the other one, a leak onto the window sill. Sorry, can't help with your problem but I'm sure someone else will have had the same and be along to help. In the meantime have you searched the forum for similar threads ?
There is a bung that can be removed which ill allow the air to escape and "dry" the inside. Replacing the bung is the hassle as people push the bung too hard and it falls inside.
Condensation is common but it goes, it might be the window is delaminating as the previous poster said.
The bungs can be taken out to help, but they easily fall inside! Not sure if new ones can be bought.

Difficult to say for sure at this stage if that is just 'atmospheric' condensation or as a result of inward leakage of water from inner and outer panes separating (delamination). Caravan windows (and skylights) differ from domestic double glazing which is hermetically sealed with a 'dry gas' sealed in, caravan windows are more like secondary glazing with a degree of atmospheric air circulating, so condensation is not automatically indicative of failure/needing replacement. We've had some vary variable weather of late with warm humid days and chill nights, which would both draw damp air into the window cavity, and cause condensation. That said, if just the one window, rather implies it may be joint leak between panes letting water in!
As said, there are small 'bungs' (mostly to keep bugs and dust out) on the inner pane, these can be removed to allow more air circulation through the window cavity, which should slowly remove the condensation if only caused by atmosphere. Gently heating inner pane with a hair dryer or fan heater may assist the drying, but be careful to only WARM the window, not get it too hot on risk of damaging it. After window has dried, wise to refit the bungs to restore original purpose of keeping bugs and dust out, but extreme care needed not to push them right through!
The often described method of removing them without risking damage to window or accidentally pushing them into the cavity (with no chance of removal!), is to grip the central 'pip' with tweezers or fine nosed pliers and carefully pull out. Replacements are easily found if needed, one source here: https://www.ebay.co.uk/itm/135335773917?chn=ps&norover=1&mkevt=1&mkrid=71015331652........
IF it is a leak, all is not necessarily lost, they can often be fixed, BUT the windows are usually Acrylic or Polycarbonate plastic, and ONLY suitable adhesive/sealants should be used, otherwise irreparable damage may be done to the plastic, with either rapid or delayed crazing occurring, which is both unsightly and weakening. Competent DIY or commercial fix depending on ability. More details on that later if you need it, as a whole post in itself!

I'm afraid that I too have a front window that suffered water ingress the same way, It turned out that the two parts of the window,(inside and out) were delaminating. Although I managed to reseal the two parts together, a very small amount of water still entered and pooled, even with the bungs out.
I mentioned this to my mobile engineer who says they see it regularly and his advice was to leave the bungs in and then drill a very small hole from the outside, (2mm or less) in the very bottom corner of the window to allow the water to completely drain away. I did this about 3 years ago and it's never failed since.

I am experiencing the same problem as Julie Rooney 6.4.25. 3 I wonder what action she took and did it resolve the problem?
I was particularly interested to note hat Monty15 offered to write a more detailed post if required. I would welcome that advice.
My Swift ChallengerSe sealed ( non opening) front window has begun to fill up with water which I presume means it has become delaminated. I intend to use a precision jewellery drill to drill a tiny hole to drain water from each bottom corner as suggested. I intend to use sealant along the top drain to prevent recurrence but can you recommend the best product? Also is there any thing else I can do ? I would be grateful for any further advice.

I am SO sorry for not replying before!! Just noticed your message 😬 Our caravan mechanic had suggested drilling two small holes at the corners at the bottom of the window. Before doing that we decided to try sealing the whole window around where the 2 laminate panels join together. Whilst not perfect, this has certainly made a big improvement...the window is clear as we look out of it at the moment, no holes drilled yet! Can't remember the brand of sealant but it was a good quality one. Hope this helps.
