My older 2012 JGC had a blind spot sensor malfunction and blank rear backup camera screen. They found the blind spot module was fried. The moduel was unplugged, a fuse replaced and lo and behold the the back up camera screen worked. They worked with me, showing pictures of the problem via text. Together it was decided, due to the age of the vechicle, to not replace the module. Saving me lots of $$$$. I need my backup camera but I am capable of looking out the side mirrors when changing lanes. Just like back in the old days. I do not feel the dealership would have collaborated with me like Ron and his crew. I trust Weaver's and will work with them again in the future.
