Blue stain

[Hallyboy]

Hi everyone, I took my 2010 Avante out of storage this week and set up on site, I have now noticed some bluey coloured stains on the wall between the front side window and the front bay window above the seats I would post a photo but not sure how to , any advice would be greatly received, I sort of guess it's probably damp but curious as to where the water ingress is !!! ?
Thanks Hallyboy

Water can get in anywhere unfortunately. Around windows, side panel joints, roof joints, locker doors, roof lights, TV aerial mounting, heater flue, etc. The ingress point is likely to be higher than the topmost part of the stain.

The stain is between the windows and not against any of them I think if any where it's from the awning rail area or the roof joint to front panel I'm more curious about the colour of the stain I've had damp in older vans but never seen it this colour it's proper shade of blue, unless it's picked up pigments from wall board but they are not blue !!!

Could it have leeched out of any fabrics? Curtains or cushions?
