Replacing washer fluid for rear 2002 Trailblazer

Does anyone out there know how to replace the washer fluid so it will work for the rear window? Is there a separate reservoir?

Thank you.

I thought the rear ran off the front main resevoir.

It runs off the same as the front. Only, it's feeding hose (or what not) is not at the bottom of the resevoir, so your rear will run out before your front does. If you completely fill the resevoir, then it should work in the rear again. Also, you may want to make sure your hose in the rear is not kinked. Mine somehow got crimped in the rear once. Long story short... check that too.

Thanks KahneFan, I'll try your suggestion!
