Windshield Washer Fluid Pump - Not Working

Year of vehicle -- 2011 Nissan Rogue SL Leather/Nav Package 2011 Nissan Rogue SV 2.5L 2500CC L4 FI Mileage/Kilometers 70k miles So I am not a mechanic, rather an engineer and found that my windshield washer pump was not turning on or displaying the PFFFFFFFFF sound, refilled the fluid. Nada out the front or the back. Figured I would check the fuse, unflipped the fuses, 2nd from the left is the washer fluid pump, tested good, still replaced the fuse to be sure. Then after that didnt work I ordered the part. Went over to nissan website, obtained the part number, ordered it for 27$ and bam back in business, just ran home to replace it. Hooked it up power wise before installing it and i didnt hear that sound again. It doesnt look like any of these are working or its power issue? The car is in great shape but I am lost as to where the issue is. Could anyone shed some light? The fluid/noise is not made when I try and wash the front or the back. Replaced the fuse, nothing, replaced the motor for the pump, nothing after the top power was hooked up. Nissan wants 150 for diagnostics and I mean I am all for their fees but would like to fix it myself. Anyone have any ideas? Can supply pictures and everything.

Have you checked for power and ground at the washer motor connector while activating the washer pump? Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

YOU ARE A GENIUS!!!!!!!!!!! It was the ground. I split it and routed it to the chasis. Its good. HOWEVER! when i activate the back wiper fluid motor the fuse pops. Even put a 30 fuse and still pops. going to take apart the back wiring.

Hold on there! The way this pump circuit operates is one wire with be power and the other ground for the front. Then polarity is switched to run the pump backwards to spray the rear. It operates almost like a window motor. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

You don't have to take the wiring apart. You could have a bad combination switch, as long as the ground from the combo switch is good. You know the wiring is good going to the pump from the combination switch because you popped the 10 A fuse when you switched polarity using the rear. Obviously your missing a ground, so you really need to make your checks at the combo switch. Here is the diagram: make sure that pin 12 has a good ground. You know you have power from the 10 A fuse. If those check good, you more than likely have a bad combo. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

Mine comes with a blow off valve rated at 10 psi. Just want to add: Don't ever put a higher rated fuse in a circuit that isn't designed to handle that type of current unless you want to burn the insulation off the wiring and cause fires. Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

It was to express that I have probably changed two tires. And I am the geeky engineer, not the post and beam kind. Learning to fix your own car gives me self satisfaction honestly So just picture me as the glasses wearing, office sitting, shy at the first sight of a girl kinda dood

It's just a standard joke in our industry because we blame the engineers for making our jobs so hard unnecessarily. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

It's the button you push to activate the washers. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ We offer help in answering questions, clarifying things or giving advice but we are not a substitute for an on-site inspection by a professional.

what is the process of taking this apart? Just two-4 screws? Anyone remember the process and how difficult it was to fix this type of issue or get to the combination switch? Thanks.
