Removal

1 Operate the wiper motor of Fiat Punto, then switch it off so that the wiper arm returns to the at-rest/parked position.
2 Stick a length of masking tape on the glass below the edge of the wiper blade, to use as an alignment aid on refitting,
3 Prise off the Fiat Punto wiper arm spindle nut cover, then slacken and remove the spindle nut (see illustration).

4 Lift the blade off the glass, and pull the wiper arm off its spindle. If necessary, the arm can be carefully levered off the spindle using a suitable flat-bladed screwdriver. If both windscreen wiper arms are removed, note their locations, as different arms are fitted to the driver's and passenger's sides.

Refitting

5 Ensure that the wiper arm and spindle splines of Fiat Punto are clean and dry.
6 When refitting a wiper arm, refit the arm to the spindle, aligning the wiper blade with the tape fitted before removal. If both windscreen wiper arms have been removed, ensure that the arms are refitted to their correct positions as noted before removal.
7 Refit the spindle nut, tighten it securely, and refit the nut cover.
