Ok I have the intermittent relay and a washer pump on my car. First ever thing is wired correctly and making good contact. Second, I know the order of the wiper switch: all the way down is intermittent, then off, then slow, then fast (well faster than slow…). Pulling the switch you get like 4 or 7 swipes and the pump comes on. That is how it is suppose to work.
Here is what I get: all the way down is nothing, then off, then slow, then fast (well faster than slow…). Pulling the switch I get the 4 or 7 swipes and the pump comes on. Thoughts? If the relay was bad would the 4 or 7 swipes still happen with the pump? Mike |

Mark,
Do you have pictures of the circuit card? I'd love to have both working. Mike |

Mark, Do you have pictures of the circuit card? I'd love to have both working. Mike Here is a drawing. The card is installed in the car so no pictures of my work. The relay is a Radio Shack PC relay with a 5A contact. The input is the Brown / Black wire from the wiper switch. It is connected near where it goes to the intermittent relay. The washer pump is grounded on one side. The output of the relay provides 12 volts. I should note I forgot the suppression diode across the relay coil in the drawing. Place the cathode to the +12 volt side and the anode on the other side of the coil. |
