Remote window down

[73gts]

Hey everyone,

New here. I wanted to know if and how I could add the remote window down with the remote if my car did not come equipped.

2008 Altima

Thanks

Hold the alarm "arm" button down for a few seconds and it should auto-down (you have to keep holding the button until it's down). I'm sure it's similar to other Nissans....

Thanks, I have already tried this and it did not work. I was wondering if I could add this feature and if so how would I do it and how much would it cost.
