The blurry side camera on your Furrion Vision S+ system is likely defective since cleaning did not improve the image and the other cameras remain clear. Because your purchase was made last year and is outside Elkhart RV Parts' standard return window, the best course of action is to contact Lippert Customer Service directly for troubleshooting and warranty support. Lippert can help diagnose the issue and determine if the camera qualifies for replacement under warranty. Be prepared to provide your order number (#10015760), a photo or video showing the blurry image, and a photo of the camera's label. If Lippert requests proof of purchase, Elkhart RV Parts can assist with that documentation. This process ensures you receive authorized support and potential replacement through the manufacturer.
