[xj40] water leak

My 93 XJ 40 Sovereign leaks water onto the drivers side footwell if
the car is parked downhill. There is no water intrusion if I park
facing uphill. I am deducing that the front drain on the sunroof is
the culprit, assuming that it is connected by tubing to drain
rainwater somewhere safe. If so, mine has obviously become
disconnected somewhere. Does anyone know if this tubing connection
is fact, and if so, where is it supposed to drain to, and of
course, how to fix it?

Thanks

Hi Mike.
You are correct in thinking there are drains for the sun roof. They run down
the respective ‘A’ an ‘C’ pillars.
If you open up the sun roof you will be able to see the oenings if they have
not been gunked up with debris over the years. My old '88 had the same
problem but I fear that the cause of my blockage was mor down to corrosion
in the passenger side ‘A’ pillar compressing the rubber tube.
Once you have located the offeding item get some strong whipper snipper line
and try to feed it down, the tubes exit at the rear of the respective wheel
openings on the front of the car.
Actually thinking about it I am not certain if the rear go to the ‘C’ or
the ‘B’ pillar, either way you will need a good 3 meters of line to get all
the way through.
Hope this helps.
Regards.
Robin

Hi Mike,

There is a rubber hose, ~3/4" diameter, which goes from the front
sunroof drain, down the A pillar, to a hose bib on the side of the air
plenum, which then drains behind the front wheel. If that hose has
been pushed off the plenum hose bib, water from the sunroof will drain
onto the top of the fuse panel (NOT good :wink:

If you look high into the corner of the footwell on that side, you will
see a trapezoid-shaped grey rubber plug, ~ 6" long & 3" high. If you
remove that plug, you will see the black rubber drain hose and the
plenum bib to which it is supposed to attach.

The description above relates to my 89 (similar leak corrected by
simply re-attaching the hose to the air plenum bib), and I presume the
same applies to your 93 model.

I’ll send you two photos offlist.
