Intermittent wiper fault

As the front wipers, like the rear screen one, is controlled on the CANbus by the Body Control Module, a hard reboot of this is achieved by disconnecting the battery for a minute or so (if the radio is turned OFF during this power down it probably won't need the security code to be re-entered) This hard reboot usually solves rear wiper malfunctions so should be the first thing to try on front wiper irregularities..........
