I've got a 1998 1.8 Xsara with a rain sensor to control the timing on the
intermittent windscreen wipe.
Trouble is, the timing is sometimes a bit wonky and varies in an annoying
way (depending on the type of rain) .
For example, sometimes it doesn't wipe the screen often as it should so
that the screen fills with rain and then suddenly wipes at double speed for
a couple of sweeps.
Does anyone know if it's possible to tweek the existing control circuit, or
by-pass it with an electionic mod to give a more consistent timing of the
