windshield washer pump runs constantly, without warning. drains battery. when car is parked
Are you asking for help or just posting your problem. If you don’t know how to fix this or even disconnect the pump have it fixed. Constantly draining a battery will cause it to fail much sooner than it should.
Could be a short in the wiring, but it’s probably a bad switch. The motor is usually on the bottom of the washer fluid reservoir. If you see an electrical connector there, just unhook it until you get it fixed.
