I can only share the information. The BCM performs control of the windshield wipers based on the signal from the wiper and washer switch. (See WIPER/WASHER SYSTEM.) The BCM performs control of the blower relay based on the request signal from the PCM.Trying to fix my wipers that wipe but don't dock, but can't seem to find anyone with in stock new or repro Wiper Motor Cover Boards for the 1984.
Anyone have a source they can share?
