Dear Amtak,
Could you confirm whether the left mirror of your car behaves similarly as the right mirrror would?
I have a Tata Nano LX 2011 model, which did not have the left mirror initially. I got one installed recently in Tata Motor Service Centre, but it does not move up and down (i.e., does not have vertical movement) and its horizontal movement is slugggish. If this is a problem in my piece, then I would go to the Service Centre based on your feedback.
Thanks.
