Do You Own an XJ Series
Saloon?
This will be of interest to you

Here are some quick remarks on some
of the more common repair issues and questions. Most of these items
pertain to the Series I-II-III XJ Saloons but you XJ-S owners may find some
useful tips, too.
Wipers don't self-park: The fault here almost always lies with
the column mounted control switch and not the "park switch: on the
wiper motor. (Ser. III)
Clunk, rattle, crunch noise over bumps: The upper bushings
for the front shocks are almost always disintegrated on these cars, allowing
the shock to rattle against the inner fender well. New replacement
bushings are available separately and many owners have successfully used
generic bushings from a local parts supply. Also check the braces,
which run diagonally from the cowl to the finders wings). Make sure
they are tight, very tight. Anything less will allow them to make
noise as the body flexes.
Power door locks inoperative or slow working: In about 80%
of the cases the recalcitrant locks can be brought back to lice by removing
the door trims and thoroughly lubricating all the linkages and sliding points.
Use an aerosol lubricant, silicone spray works well. (Series II &
III)
Vibration felt when brakes applied: This is usually caused
by warped brake rotors. Rotors can often be taken to a machine shop
and be resurfaced but most owners replace them with new ones. The
new ones are not too expensive and, since the job is labor-intensive., it
makes sense to just install new ones.
Speedometer inoperative or erratic: In about mid-1982 or so
(for North American market cars, later for rest-of-world_ Jaguar switched
from a cable-operated instrument to an electric one. A transmission-mounted
transducer produces a signal that is sent to the speedometer. This
transducer is the most common culprit when your speedo acts up or just plain
quits. Of course the connections should be checked first. (Series
III)
Cruise control does not work: There are many possibilities
here but often the fix is easy. First, check the 2 amp fuse (#12 fuse,
main fuse box). Next check the vacuum bellows. This often leaks
at the edges and can be cleaned and resealed with silicone sealer.
Do not forget to check the vacuum supply to the bellows. |
