Hi @mohammedse91958
Could be a faulty (sticking?) wiper on/off relay in the engine bay fuse block.
Try removing the R4 relay¹ (if gas engine) or R1 relay¹ (if diesel engine) and check that the wipers don't start by themselves.
With the relay removed they shouldn't operate at all.
¹ Check the fuse layout diagram in the fuse block lid (or owner manual) to check which relay is the wiper on/off relay in your vehicle.
