I have an 09 reg Ford Ka, which has so far passed all MOTs and has had no problems. Recently (in the past 2 weeks or so) the front windscreen wipers have started to work strangely. Sometimes when I start the car and turn the windscreen wipers on, the front ones won't work.
Other times they work fine when I initially turn them on, but then stop working of their own accord. I then have to turn them on and off, and adjust the wiper speed several times until they start again and this can take minutes.
This does not alway happen, sometimes there are no problems at all, but I'd say there's a problem 60% of the times the wipers have to be used.
There is no problem with the back wiper.
It seems to be an electrical error, but what?
Any help or clues is greatly appreciated.
