Hazard

Due to improper electrical circuitry in the windshield wiper system, when the operating speed is switched near the stop position during wiper operation, a voltage differential can occur across the relay contacts in the electrical circuit, generating sparks. This may cause excessive current to flow through the electrical circuit, resulting in fuse burnout or relay contact welding, which could prevent the windshield wiper from operating.

窓ふき器において、電気回路が不適切なため、窓ふき器作動中に作動速度を停止位置 付近で切替えた際、電気回路内のリレー接点間で電圧差が生じ、スパークが発生することがある。そのため、電気回路に過電流が流れてヒューズが溶損若しくはリレーの接点が溶着し、窓ふき器が作動しないおそれがある。

Remedy

All vehicles: Replace the relay and harness with corrective parts and modify the electrical circuit.
