Will this bolt directly to my door without welding or drilling?

Yes. This assembly is engineered for factory mounting points — no modifications needed. Unbolt the old regulator, slide the new one in, and secure it with existing hardware.

Do I need to remove the door panel to install this?

Removing the door panel is the standard approach for window regulator replacement on this platform. You'll need access to the interior door cavity to reach the mounting bolts and disconnect the old assembly.

What if my window motor is bad but the regulator is fine?

This is a complete assembly — motor and regulator together as one unit. If only your motor failed, you're replacing the entire mechanism. For partial failures, confirm which component is actually faulty before ordering.
