    Isn't getting power. I only see one fuse for a washer and the front one works. Is there a relay? Does any hane a schematic for wires from stalk? Or know color of wires for rear washer? Is there a separate fuse for rear washer like there is for rear wiper?

    And some cars you can just swap the front and rear pump the plugs and all are the same and if it swap doesn't work then you know generally the pump is bad if the jug is near empty anyway I'm not going to really lose anything as far as washer fluid goes and it just pop out with a screwdriver or any kind of prying tool.

    I'd do what Tom said. Maybe cross connect the output tubes and see if there's a blockage too.

    No relay. +12 comes to the washer motor on the violet wire from 2C pin 3 at the in-dash fuse box (from the RR WIP fuse), and the blue wire from the motor gets grounded by the stalk switch when you want a squirt. (Blue wire passes through pin 13 of AL4, pins 2 and 1 of L86, and connects to the stalk at pin 5 of L48.)

    Usually on any car if I have one of those washer jugs with two pumps in it and one isn't working I just moved the cord from the pump that's not working to the pump that is working to make sure power is coming and it powers the pump that the other plug was just plugged to a second ago and vice versa just eliminates everything except the pump and then I usually walk out into the carport where there's a few of these jugs laying around that need to go to the trash pop the pump out and pop it in and place of the one that's not pumping plug my wires up to it and off we go I don't think I've bought a new one of these things ever they're always out of other cars I'm sure they make them and they're no problem to get and all the wiper companies make them I see them hanging on the wall but you would need to carry yours in to get the right shape to press into your jug.

    Since I don't have 12 volts at the electric motor, I'm going to trace this one backwards

    Is this for the rear washer or the front? Seems like the stalk switch may be the culprit. Any other funny issues with the clock spring or anything that the clock spring would make connections for?
