Clearing blocked sunroof drains

[RetroPug]

Do the pipes run into/past the rear arch, i've got what looks like salt/old water deposits around where the rear speaker connector is... (hope that makes sense haha)

Not sure, but this could also be your rear window seals not sealing properly.

Thats how you know you own a Peugeot!

My neighbours probably just think that I'm an idiot...there are proper, full parking spaces on the edge of the road and I still park mine in the space but slightly on the kerb.

I've heard that the problem could also be that the drain pipe is improperly routed and could be trapped/pinched closed somewhere, it is entirely possible that when the cambelt was done before I bought it that it could have been tucked out of the way (the blocked one is on the same side) when the wheel arch was removed to gain access. I will be checking this as well but have no time for a few days.
