WINDSHIELD WIPER DIAGNOSIS - PULSE WIPERS - SERVICE MANUAL UPDATE
1984 THROUGH 1987 SUNBIRD MODELS
Starting in 1984, the Sunbird wiper motor pulse module was eliminated. The pulse function electronics were moved onto a printed circuit board that is
installed on the wiper motor assembly. The On-car diagnosis within the wiper motor service manual sections contain references to a separate pulse
module which is incorrect. The charts that are affected are Condition No. 1, 2, 3, 4, 5, 6 and 7. When performing diagnosis on a pulse wiper system, use
the diagnosis provided in the Electrical Troubleshooting Manual (1984-1985) or service manual section 8A (1986-1987).
Please mark-up the affected pages in the wiper motor section with references to this article.
