How to Replace a Power Mirror in a Hyundai Sonata

Lower the side window of your Hyundai Sonata all the way down, then disconnect the negative battery cable.

Unsnap the triangle mirror panel inside the door by prying it off with your hands.

Remove the three bolts that hold the mirror in place using a screwdriver and wrench if necessary.

Unplug the electric connector to the mirror. Pull the mirror completely out of the assembly.

Place the new Sonata mirror into place, and attach the mounting bolts that hold it in place.

Re-connect the power wire by snapping the new connector into the power source you disconnected the old connector from.

Put the interior mirror cover (the triangle piece) into place by pushing it back in until it snaps into place.

Connect the negative battery cable as your last step, and test your mirror to make sure it works.
