Xantia wiper query

All,
I have a 99 Xantia Est. Hdi ...
The wipers work fine on Intermittent or Fast Continuous, but on Normal Continuous their motion has become very "jerky/sticky" with longish
(1-3secs) periods stationary/stuck randomly during the sweep.
I imagine the motion limit contacts/microswitch have become loose/dirty/broken in some way - and on Fast mode the momentum of the system is enough to 'get it over the switch' and continue working fine ...
Any ideas our there?
Yours hopefully
Steve
