I have an early XJ-S December 1975 pre-HE (France) and my feet get wet from
the wiper box.

I’m prepared to stand corrected on this, and i don’t think I have rod’s original
posting here for some reason, but i believe that air vents inside the car pick up
air from in the wiper box.

normally water doesn’t get into them. however, if, as pascal suggested, the drains
were blocked, or if, as i discovered, you blast the region with a high pressure
hose, water can make its way toward the vents.

however, it doesn’t make it all the way; presumably pipes which are adequate to
send a blast of air into your face aren’t necessarily water-tight - somewhere
there’s an unsealed join and the water drips out into the footwell.

I haven’t checked this physically, it’s an assumption i made based on the high
pressure water hose experience, at a time when i had other things on my mind!

One thing though - big fat pipes like the wiper box drains ought to be pretty easy
to unblock. Holes at the lower front of the box run into some big rubber bootlike
things in the engine bay that then join to metal pipes. i’d suggest that join as a
candidate for blockage, and I’d say you could blast it clear.

I’ll check this tomorrow (my car is at my old man’s house, i have only street
parking here) and either eat my words or retain my confidence.

As to the rest… yes, a comprehensive thread on leaks might be an idea, and I’m
sure I can contribute to it!!

Cheers all,

Check this out

The A/C Heater unit has two drain tubes which drain water - condensed
during air conditioning - out of the unit, as well as water that may
enter the intake vents by other means.
I reckon yours may have got blocked. probably thru foreign matter such
as
leaves etc being sucked into the air intake in front of the windshield.

This happened to me.

If you get your body under the car you will see two tubes, one each side
of the gearbox. Poke a length of welding wire up each one (about eight
inches) and dodge the deluge of water.

Good luck
