If your windshield is dirty, driving your car will feel like you're looking through contacts that haven't been cleaned in a month or dirty glasses. We'll tell you how to keep your vision sharp and unobstructed on the road this week in DIY Garage: Vision Basics.

AOL Autos has teamed up with AutoZone to bring you a series of DIY car maintenance tips and tricks, straight from our garage to yours.

The DIY Garage video series covers common questions like how to change your own oil, or what the source of that pesky puddle on your garage floor might be. Host and AOL Autos Editor-at-Large Rex Roy will explain everything in plain English and is sure to have some fun along the way.
