Too far back in the cab and too high to be screen or door seals (stationary when rain started) reckon it's probably the seal around the front bolt of the roof bar.
Still, while the lining's out I can have a go at fixing the front sunroof's bent runner I guess.
To top the day off I lost all behind-the-centre-console lighting (pain in the arse to fit new bulbs on a '95 ES) and the cruise stopped working for about 1/2 an hour. That really annoyed me cuz I only go it working at the weekend!
Seems fine again now but bloody odd driving with a dark cab and just the green of the dash!
