Seeing as the description says “If it leaks it’s in here” I’m putting this in here!
Whilst removing the interior trim from my P38 to clean it today I found that the drivers side carpet is wet... very wet!
I’m struggling to find the source of the leak though.
This is the only place I can find any sign of it being wet near the door. Under the wiring harness towards the front and rear of the car from that point is bone dry.
The wetness seems to be coming from the transmission tunnel side but I could be wrong. When squeezing it and licking my finger tips the water is fresh, it’s not coolant so that rules out heater matrix o-rings.
I removed the trim on the top of the windscreen and both roof rails that run from front to back, there’s no marks at the top of the body and when soaking it with a hose there’s no water coming in. The pollen filter is dry and when looking under the flap at the blower motor it’s dry as well. When soaking the scuttle panel with the house the pollen filter housing and the bulkhead up behind the pedals stays dry as well.
I dropped the headlining and took the sunroof drain tube off, it’s bone dry and isn’t blocked either.
The air conditioning hasn’t yet been charged so it can’t be condensate either.
The car hasn’t been used in the last few weeks but we’ve had a couple of days of very heavy rain so I can only guess that it’s rain water that’s gotten into the cabin somewhere but I can’t figure out how!
Has anybody got any suggestions where I could look next? I’ve done so much work to this car recently that this has really wound me up today as I was hoping it was going to be an easy fix!
