I was cleaning my car, and moving the driver's seat forward and up so that I could vacuum behind it. The plan was to move it as far forward and as far up as possible to get the as much access as I could to clean all the nook and crannies. Didn't expect the seat to move far enough to damage anything, so I wasn't watching the top of the seat. Instead I was watching the bottom so I could see when it stopped moving in each direction. I discovered the hard way that, surprisingly, it is possible to push the headrest right up into the sun visor with enough force to shatter the vanity mirror! If you want to try this yourself (why would you?)... Start with the seat bottom all the way down as far as it will go. Tilt the seatback as far forward as possible. Then, tilt the back of the seat bottom as high as it will go. Finally lift the seat bottom up while watching the headrest. You'll discover that the headrest will come into contact with the visor, and that you'll still have some travel distance available to you. If you continue to raise the seat bottom, you'll hear a cracking sound and the mirror will be shattered. Note that when this happens accidentally, your heart will sink as you instantly fear that you've cracked the glass roof. Then as you glance up and see where the top of the headrest is, you'll realize that it was ONLY the vanity mirror. All that being said... Does anybody have any experience with replacing that mirror? Will I need a whole new visor, or can I just replace the mirror? How much might it cost? I'll be calling the service center tomorrow morning.
