Rear window washer

Yes it’s hums

Same question. The pump hums for the front windshield fluid dispenser and squirts well. When i push the seperate switch for the back window washer it is a different hum and no fluid. I’m flomixed!!

Likely there is a check valve that is clogged. It will be located right behind where the hose exits from the rear gate to the rear windshield wiper. Unfortunately you'll need to remove the plastic trim from the interior. It's a major pain. You can either replace the check valve or just remove it. If you remove it, you'll need to wait for a while before the rear wiper has water.
