1990 Chevrolet Blazer Q&A
1990 Chevrolet Blazer Question: What would cause the windshield washer fluid to continue to spray?
1983 K5 blazer full size. The wipers work on low and high switch setting. When I push in on the switch for washer fluid to spray, it will spray until the wipers are turned off. If I turn the wipers back on, the washer will still spray without activating the washer. It will continue to spray until the wiper switch is cycled on and off three times then stop spraying. The wiper motor/washer pump unit has been replaced 3 times with re-manufactured units. The wiper/washer dash switch has been opened and cleaned internally. The wiring harness terminals at the firewall have been cleaned and di-electric grease applied. None of the above measures have fixed the continuous washer spray. Any ideas on testing and/or repair would be appreciated! - lightsaber
