I have just bought a 2001 Ibiza 1.4s. The windscreen wiper only works in the fastest setting and won't park itself. Rear wash wipe works fine. Quick review of posts seems to suggest either the relay (number 19), the operating stalk or the motor are at fault. To avoid replacing them all unnecessarily any advice from members as to which it is most likely to be? Also are these Polo/Ibiza parts interchangable Thanks.
