Help. I've replaced the washer pump, the "hook" that engages the switch isn't stuck, the ground is good, but for some reason the park magnetic switch doesn't seem to engage. If I contact a ground to the top of the three terminals (light blue wire) the switch will disengage the hook. The motor is new, the pump is new, the dash switch has been replaced. The motor keeps "clicking" even in the off position. This is becoming a crusade and I'm losing the battle. Can anyone help?
