A vehicle wiper system includes a drive mechanism, a wiper and a gutter each connected to the drive mechanism, and a locking mechanism. The wiper has a stowed position and an extended position. The drive mechanism reciprocally moves the wiper about a pivot axis to sweep a defined area of a windshield. The drive mechanism moves the gutter together with the wiper about the pivot axis between a stowed position and a deployed position wherein the gutter extends along a lateral edge of the windshield. The locking mechanism is configured to lock the gutter in the deployed position allowing the gutter to be statically disposed at the deployed position while the wiper is reciprocally moved about the pivot axis.
