Mysterious leak

[Gardiner]

have had a leak somewhere in my brumby and is pisssing me off. It seems to come from behind the windsceen somewhere and works its way down the plastic and all the way under the floor mats. Its not much but bloody annoying all i can find is a small crack in seal on the inside of car would that be the problem

Has anyone else had the same problem and is there any solution? Should i get the windscreen re-sealed???

By the way has anyone ever ripped out the standard mats and done anything creative mine are alll warped and stink
