Washer Fluid Leak - 2002 Blazer

I parked on on incline this afternoon and noticed a fluid leaking at the back corner on the driver side. About a pint leaked out. It is windshield washer fluid. I looked up under the vehicle and noticed a wet spot on a hose, but the hose seems to be a lot bigger than what would be used for washer fluid.. Is there a rear fluid resovoir back there??

I never use the rear window wiper or washer.

Any help would be appreciated.

There is no rear reservoir for the washers, front and rear use the same. If you have a drop down tailgate, either the hose is disconnected in the tailgate or under the floor trim plate. The rear washer hose runs under the carpet, the hose that you see under the vehicle is probably for the emission EVAP system.

Thank you very much...
