Windshield wipers on a Chevy HHR work to clean mud and other debris from your windshield. They also increase visibility when it's raining. The rear wiper is primarily used for clearing dust, dirt and mud from the back window. They don't typically get used a lot (since drivers spend most of their time driving forward). However, they will need to be replaced eventually. You should check the rear wiper blade on your Chevy HHR at least once a year. The frequency with which you need to change them will vary depending on the weather conditions and the amount of time you spend driving. When the time does come for you to get a new rear wiper blade, you'll need to know how to change the rear windshield wiper on a Chevy HHR.
Pull the wiper arm away from the rear window. The wiper arm is spring loaded on most Chevys, so you'll need to pull until the hinge folds and the wiper arm can stand on its own.
Lift up on the clip at the wiper arm connecting point. Pull the wiper blade toward the windshield to remove the wiper blade.
Install the new wiper blade and push down on the clip to lock the blade in place.
Lower the wiper blade and arm to the rear windshield.
