On my '09 Chevy Traverse, the windshield washer pump stopped working on both the front and back. I first checked for fuses. There was one in the fuse block under the hood, that one looked good. I found another under the dash on the passenger side (what a PITA to get at). That one was blown. I replaced that one and now the rear works. When I try the front, I hear a click (a relay?) but nothing else happens. Any idea if there is another fuse somewhere label incorrectly or where I should look next?
So I replaced my pump... and it still didn't work. After doing some more looking I discovered that I read the fuse map wrong and put the fuse in the wrong spot. After putting it in the right spot it started to work. Since I know you can't take used electronic parts back, I just kept it in and kept the old one.
BTW, to get at the pump, you have to remove the wheel and open up the wheel well.
