Will this work with my CR-V's existing door panel?

Yes. This is a direct replacement for the original switch cavity. The bezel and mounting points are factory-matched — no modification to the door panel required.

Do I need any tools beyond a screwdriver to install this?

No. The switch clips into the factory pocket after you disconnect the old one. You'll need a trim tool or flat screwdriver to gently pry the door panel trim if necessary, but most installs are straightforward.

What if the window doesn't work after I install it?

Check the connector seating first — push it in fully until you hear a click. If the window still doesn't respond, test the door's window motor separately. A dead motor is separate from a bad switch. If you suspect a defective switch, contact ModSupply for return options.
