I hope this is of some help! The wipers on my 1999 306 recently started\nto 'stutter' when about to park, either from switching off, on rain\nsense or just single wash/wipe. All Peugeot user's web sites showed\nthis as a common problem, with both dealers and owners blaming water\ningress.\n\nMy wipers ran OK when switched on so I wsa confiden they would not let\nme down. I left them to let the fault develop into something\nrepeatable. I was definitely the self parking relay contact within the\nmotor. It was about one hour's work to remove the motor and open it.\nThe relay consists of three metal fingers, value about 0.5p, one of\nwhich had burnt short my spark errosion. Two needle nose pliars were\nall that was needed to reshape the end and refit. The wiper is now as\nright as rain! The work was simple, nothing will fall out of the motor\nwhen you undo the cover (4x small screws).\n\nTools needed: simple gear puller to remove wiper arm (mine were stuck\non the spindle) Do NOT try and lever them off else you may crack your\nscreen!. Allen key/Torq blade to remove plastic trim, assortment of 6,\n10 and 13mm sockets/spanners, two pliers. Saving £100 on new motor.\n\nWhat is needed now to prevent this happening again is to use the\ninternal contacts to control an external, high current swtiching relay.
