The carpet has very thick stiff sponge base and awkward and time consuming to remove.
Thread revival!!!

My yellow grommet is kaput! By "smash the plastic enclosure", do you mean remove the grommet, then using a load screwdriver or similar implement pointing forwards towards the engine, pierce a hole as low down as possible in the next layer a few inches beyond where the grommet would sit?

If I reach inside the cavity behind the grommet, I can feel a drainage hole at about the 7 o'clock position which leads to behind the arch liner (or so I'd imagine). I've poked a big thick cable tie down that hole and all seems clear. Next job is to remove arch liner and clear out anything that side. Got Tigerseal and a grommet on order! Just curious about your tip about making a hole!
