The invention discloses a windscreen wiper circuit. The windscreen wiper circuit comprises a windscreen wiper switch, a windscreen wiper high-speed relay K2, a windscreen wiper low-speed relay K6 and a windscreen wiper motor. The windscreen wiper switch is provided with a high-speed gear 53b pin and a low-speed gear 53 pin. The high-speed gear 53b pin of the windscreen wiper switch is connected with a driving end K2.86 pin of the windscreen wiper high-speed relay K2. The windscreen wiper high-speed relay K2 is connected with a 53b pin of the windscreen wiper motor and drives the windscreen wiper motor to rotate at high speed. The low-speed gear 53 pin of the windscreen wiper switch is connected with a driving end K6.86 pin of the windscreen wiper low-speed relay. The windscreen wiper low-speed relay K6 is connected with the 53b pin of the windscreen wiper motor and drives the windscreen wiper motor to rotate at low speed. The driving end K2.86 pin of the windscreen wiper high-speed relay K2 is connected with the driving end K6.86 pin of the windscreen wiper low-speed relay K6 through a diode. By means of the windscreen wiper circuit, a windscreen wiper resets in place, and intermittent operation is accurate.
