The design of the gear motor allows it to be disassembled to eliminate minor faults (collector cleaning, etc.).
The rear window wiper connection diagram is shown in Figure 7-40. The rear window wiper and washer operation is controlled by switch 3 (lever position see figure 7-34).

For the rear window wiper, with a gear motor load of 1 Nm, a supply voltage of 13.5 V and an ambient temperature of (25±10)°C, the number of double strokes of the gear motor shaft in intermittent mode should be 16...18 min⁻¹, in continuous mode 20...30 min⁻¹, and the current consumption should not exceed 3 A.
