Why would a power mirror turn black?

It sounds like you have a auto dimming mirror and it lost it's fluid.

It's not auto dimming or heated.

reflective material all flaked off?

is this an adjustable one, such that the anchor point MUST be in the center of each mirror mounting point?

someone stole your mirror during the night...it's easy with these powered ones to just "snick" and the prize is yours~

must have fallen off while you were driving. That's what the pop was, if you looked back would see it lyin' in the road~

easy to be mistaken with the "shroud" around the whole assembly, you cannot tell if there is even a mirror there except to hit the adjuster~

that's right ,the reflective glass glued on the backing pad fell off and hit your door and went pop, now what?

Buy and new glass.

Here's one for $21 -- http://www.ebay.com/itm/2004-2006-VOLVO-S80- PASSENGER-RIGHT-MIRROR-GLASS-5222-/300708973735? pt=Motors_Car_Truck_Parts_Accessories&hash=item4603a6cca7&vxp= mtr

we kick ass, you guys!

Thanks everyone. When I got home I looked closer, it loss like the mirror popped off. Replacement glass is on its way.

when I hit a blue recycle bin avoiding a deep pothole the mirror shattered, bent back and the actual mirror piece was found 200 yds away, spider cracked but operational....later paid tire pros to do the replacement, three bolts way up in there have to undo the door liner and all that...just pay a guy, yknow?

good thing MINI has the same design for almost ten years, made finding a replacement unit cheap and plentiful....all and all 40 for the replacement unit 100 labor set me back 140 just because Clearlake is too cheap to fix the roads around here~

Where can I find a mirror for a 2006 Volvo V70 on the driver side I heard a pop and then the mirror turned black can't see a thing
