Since we had this type of failure 4-5 years ago & warranty covered them a $500-$700 mirror isn't a big deal. But now when they break & the car is out of warranty YOU don't want to spend $$ for mirror. The mirror will have to be removed, disassembled, & repaired. I came up with a good repair by securing the mirror retaining straps to plastic housing w/tiny sheet metal screws. Again taking time & being careful w/plastic is important.
