would you be able to explain to me were this grommet is i nearly tore off all the headling today cant find this leak anywhere and there is a lot of condensation going along all the metalwork and leading into the cabin and i want to fix this before the interior gets damp and smelly and there was a big enough puddle in the spare wheel well but the carpet covering the well does not get wet and i sealed up the tail lights so im hoping its the grommet you're talking about any feedback would be much appreciated thanks
