The rays of the sun do more than heat up a car's interior. Outside, those rays oxidize and dry out the rubber windshield wiper blades. In time, the blades dry so much that they crack. Don't expect them to perform at 100% efficiency when dried out and brittle.
The way to deal with the problem involves replacing the old blades. A technician removes the worn blade and then installs new ones. The replacements must, of course, be the right fit. You don't want to pick the blades. Leave that task to the technician. Once new blades are in place, performance troubles should no longer be an issue.
Don't find yourself caught by surprise. Ask service department workers to check the windshield wipers every time the vehicle undergoes routine. Stay on top of things and avoid unwanted safety problems when driving in Portland, OR.
