As above, lift the carpets including the under boot floor storage area and the even lower areas where the spare wheel and the rear washer bottle (cracked and flooded?) sit.

Once found where the water is gathering might give you a pointer where its coming from, sunroof or blocked drains is my guess with water coming down through the front bulkhead vents, 940's have good proper gutters so should be an easy trace.

Remove or lift carpets as best you can and leaving a couple of windows slightly ajar leave an electric fan heater running for a couple of days pointing at the wet part in there over the break.

If you don't dry it properly like this you won't get it thoroughly dry before next summer, and have windows iced up inside to look forward to when winter arrives proper.

As you know you should have done this when the weather was nice..;)
