Not an uncommon fault if it is what I suspect, though I note you have a T3 and this applied certainly to T1 and T2 cars.

If you haven't upped the strength of the additive to prevent freezing in advance of adverse weather, then the washer fluid has possibly frozen in the roof lining.

You've then used the rear wash/wipe and on earlier cars there was connection that is somewhere just above and behind the rear seat backrest which can pop so each time you use the washer you fill the headlining.

A good dealer should know about this and on the older cars it takes about an hour for them to drop the headliner and remake a good connection.

There's no guarantee this is exactly the same on the T3 but then again the symptoms are similar.

For anyone else reading this, if you haven't already done so and winter temperatures are dropping, then up the strength of your washer additive NOW!

 

The problem has been found!

There is a connection (maybe a stop-valve?) right at the D pillar at the roof on the passenger side which came off. I'd be glad to send it to someone's phone for posting, because I don't know how to get it onto the forum from my phone.

The speculation is that the line froze, but I've had winter fluid in the lines, and pumped it through them, since summer.

Indeed the roof panel was discolored, though not wet. If anyone has any questions I'll be glad to answer them - and thanks for the suggestions received.

 

Thanks for your reply noobytoogy, but yes, the fluid I was using was -25 winter fluid, and it had been so for a number of months.

Also, the headliner is dry.

Now I'm really confused as to what is happening!

 

I can report I've just had the same issue in my T3 (2012 Lux). Drying out the boot now and taking it for repair next week. I'll report back for the record when I know the root cause of the problem.

 

Hi I have same problem except seems to be leaking from close to wiper motor on rear door. Did you find where your leak was?

Cheers
