So my wife has a 2015 and the rear washer won't squirt. Front works fine. I took the lines apart at the nozzle at the lift gate under that panel and there's two lines coming from the tank by the hinge for the hood passenger side. I shot air through the one I determined that was for the back window and it seemed fine. I had her in the car working the controls. When she activates the front wipers you can hear the pump easily and it'll shoot fluid across the driveway with the line disconnected but when the rear is activated no fluid and you cannot hear the pump. Are there two pumps in these things or a fuse I need to check or something?
This all started when she ran out of washer fluid. I put a gallon in and the back one stopped working. Makes no sense. Thanks for your advice ?
