Any electricians about ?

My 2003 punto does not have an intermittent rear wipe and only one setting on the front . In my local scrappys there are some with the function an the stalk , so question is if I replace my stalk with a different one would I have the function ? I have read that it is the stalk that controls the functions . I have had a look on line and from what I can find out there is one wire missing between the stalk that has the function and one that has not . Can any one shed any light on this ? thanks for looking

Not sure about the Punto but many cars have a separate relay in the fuse box area to control intermittent, the stalk is just a switch that enables it.

Look for a wiring diagram for your car online and the mystery will be solved for you.

Thank you for the advice, those diagrams are as clear mud to me but I will find one see what I can work out
