However, it's *not* always easily visible. You might need to:
* Look closely around the windshield washer fluid reservoir: It's often near the main reservoir, but smaller.
* Consult your owner's manual: This is the best source of information for your specific vehicle. It will have diagrams and clear instructions.
* Search online for a picture: Searching "2007 Chevy Trailblazer rear washer fluid reservoir location" on Google Images might show you exactly where it is located on a similar model.
If you can't locate it after checking these places, consider taking it to a mechanic or auto parts store for assistance.
