Yep the PO of my SD steel wooled the mirror on my right. Bothered me forever then I just kinda forgot about it. I got a replacement at the pnp and noticed that it was heated (had a connector on the back). I never installed it and lost it so I have no idea whether my 81 has heated mirrors. If anyone knows i would love to know. The w126 does have heated windshield cleaner nozzles though. What turns them on? I Have to fix the wiring on mine but Im curious how they turn on. My friend and fellow forum member nick thinks that they probably heat only when you use them which makes sense to me. Id like to know...
