The rear window washer on my Burb doesn't work. When parked, engine off, key on, when I hit the rear washer button, I can hear the pump running just like when I hit the front washer switch, but nothing comes out the nozzle, and there is no sign of water dripping from anywhere else on the rig to signify a leak.

Does anyone know where the little hose is routed on the truck so I can trace it?

 

i know it runs beside the battery under the hood. not sure where it goes from there. its ride beside the bat and the fuse box tucked up unded the edge of thefenderl.

well thats how it is on my 03 hoe

 

Might be an obvious question but have you checked the water level in the washer bottle?On my Blazer the rear window pump is higher up than the windscreen one. Low water then means the rear one dosn't work but front one does.
Mind you on my blazer the rear washer isn't working but the pipe has come apart somewhere by the engine bulkhead and tips the water on the road if I run the pump.

 

Bottle's full. I've tried it numerous times over the last year, different fill levels in the bottle. I can always hear the pump run, never see water come out anywhere.
