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!
What would cause the windshield washer fluid to continue to spray? on 1990 Chevrolet Blazer

Replace the switch!
Do you know of any switch setup that will have delay option as mine does not? Thank You Pushrod
You mean you want to add delay wipers?? .. If so then yes....It's doable!!
Awesome! After years of turning the wiper switch on and off every few seconds while driving through light rain, I'd really enjoy a switch that has wiper delay since the original one is defective anyway. Thanks again for your advice!
You will still have to fix the wipers!... NAPA part number for the original stock type switch is WS 1004SB... Then you can add 'delay wiper control' that is available on eBay... They work slick!!! Easy install..... IF installed in dash, can't tell it's not factory... If that matters... IF you want a factory look, let me know!
