This motor does exactly what it sounds like – it powers the rear window wiper. It’s responsible for swinging the wiper arm back and forth, clearing rain, snow, and grime off that back window. It also controls the speed—so you can have a gentle wipe or a faster one when things get really messy. Some even have a washer function built in, so the motor also runs the pump that sprays fluid onto the window. Think of it as a little helper for visibility. A clear rear window is important for seeing what’s behind you, obviously. It’s a relatively simple system, but crucial for safe driving, especially in bad weather. The motor receives signals from the wiper stalk inside the car and translates that into movement. It works with a linkage to physically move the wiper arm. You’ll notice if this thing goes bad pretty quickly. Usually, it starts with slow operation, maybe the wiper gets sluggish. Then it might stop working altogether. A clear rear view is a safety thing. It’s not something you want to ignore. If it’s freezing, a broken rear wiper can also cause ice buildup, further reducing visibility. These motors can wear out over time, especially with constant use. If you need to replace yours, places like Fixparts Online are a good source for a reliable replacement.
