Well...I ultimately got the issue fixed but the people at Hans Hyundai would not explain me the reasons for the trouble, besides speculating that manually opening the mirror could have caused it (which was done only once after new OVRM was installed and that too, by the service chaps, not me). OT
: Hans Hyundai workshop/body shop in Delhi fix one problem and create another. They fixed the OVRM opening but then, the wipers, which were working perfectly earlier stopped working ... they fixed they wipers and now, a new problem with OVRM in that, the electronic adjustment from inside won't work sometimes (I guess all related electrical issues). And to top it all, instead of recognizing a problem, they just try to avoid it saying its natural or it'll go by itself or sometimes even try to pass off telling, there is no problem at all !!!
