I also suggest you examine the wiper linkage system. It is a well known problem with the Punto MK II. The ball joint mechanism is prone to wear and it is very common for these to fall out leaving the mechanism disconnected from the arm that is connected to the motor. You can visibly diagnose this by simply lifting the bonnet whilst operating the wipers and check for any movement of the linkage system.
