What could be the probable reason for the issue with the rear wiper on my Chevy Blazer?

The Chevy Blazer's rear wiper may stop working due to two possible causes. The wiper motor might be damaged and unable to move, or more likely, the fuse that powers it has blown. To access the fuse box located under the car's hood, you'll need to first open the hood and secure it in place. On the right side of the engine compartment, you'll find a black box or case with a visible seam. Opening this box will reveal the fuse inside. The back of the box's lid should display a diagram indicating which fuse is for what function. If the diagram is not on the lid, you can refer to the car's owner's manual. Once you identify the necessary fuse, gently remove it. Check if the thin strip of metal connecting the two raised sections of the fuse is intact. If the metal strip is broken, the fuse is no longer working and should be replaced. If the metal strip is still connected, the fuse is fine and can be reinserted into the box. Replacement fuses are typically inexpensive, costing around 10 dollars.
