I have a 64 Cadillac Deville convertible. When the wiper switch is turned on the washer pump activates continuosly no mater what speed is selected. Washer pump shuts off when wiper switch shut off. Ideas where to start the search or common problems with this? Larry

    Hi Larry,

         The good news is that your washer pump is working; that's usually the problem.  The continuous running with the wipers on could be the washer switch itself.  Make sure to check the wires from the switch to the washer pump itself through the firewall (that nothing is split - sending juice to the pump).  Also, check that the copper ground strap from the washer motor to the washer pump us good and not broken with age.  Mine was and replaced it along with a rebuild of the washer pump.  Hope this helps.

      I suspect that the push button is stuck or the ground wire is shorted. The pump has constant power, but it is the ground connection that activates the pump. Pushing the button in connects the ground.
