Do I need any fasteners or hardware to install this?

This assembly uses factory mounting points, so fastener type and size match your vehicle's original setup. Confirm your hardware before installation — if anything is missing, source replacements from your service manual.

Will this regulator work if my window tracks are damaged?

A new motor and regulator won't fix bent or worn tracks. Inspect your door's window channels first — if they're bent or corroded, the new assembly won't operate smoothly and could bind or fail prematurely.

Do I need to disconnect the battery before removing the old one?

Always disconnect the negative battery terminal before working on any power window system. This prevents electrical shorts and accidental window movement during removal and installation.
