My 2005 nissan sentra has hand straps above the doors. The front passenger strap became undone on one end. Is there an easy way that I can re-attach the handle?

had to install a driver side non folding mirror, fairly simply to say the least. There's a cover on the interior of the door, near the window, remove the cover, remove the 3 screws, need i believe a 10mm socket. If a power window, unhook the circuit. Replace new mirror.

Lift up the handle, you will see the bolts there, You will also have to pry off inside door panel (after removing any screws) than you will have access to the nuts. That's all there is to it.

SOURCE: how to remove front passenger side interior door panel

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

On the inside trim, you can remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. You'll need to lift the door panel upwards in order to get it off the window ledge.
