Slide-out camera mirror on rearview ...

[Hmmm2]

Thanks 8500lbs. Makes sense. I'll head to the dealer. There are about 20 little wires bound by electrical tape behind the mirror. They look pretty tight in there, but as you say, one may be loose somewheres. Hopefully I can wait while they check it out. The funny thing is is that I never thought I used that camera mirror much as it's not a true measure between the rear mounted tire and the vehicle parked behind you. But now that it's malfunctioning, I need it.
