When the windshield wipers on your Toyota Highlander malfunction, you could find yourself in a very dangerous position—especially if it happens while you’re driving in a rainstorm. The wipers on your Highlander should be checked every 6 months to make sure that there are no signs of chipping or cracking on the wiper blades. Replacement wipers can be purchased from most auto parts stores. However, before you replace anything, troubleshoot the problem.
