Now for the difficult part - You have to remove the hat deck without breaking it. It's not so hard. It's very flexible, and the only spot likely to break is the thin part right in front of the speakers. This is easily repaired with a splint and some wood glue if it should crack. Bend the hat deck upwards in the middle, and get your hand underneath it. Then gently pull one side forward until it clears the C-pillar. Reach underneath the hat deck and unplug the wire going to the shade motor. Lift the plug receptacle in the brake lamp mount straight up to free it from the brake light mount, and then poke the wire down through the hole which it feeds through. Tada! You have now removed the hat deck! See pictures 1 & 2.

Now bring the whole hat deck inside and place it upside down on a nice CLEAN bench.

The shade mechanism is attached to the hat deck with four nuts. Remove the nuts and separate the shade mechanism from the hat deck. Three flat-head screws attach the motor to the shade assembly. See picture 3. Remove the three screws being sure not to lose the 6 washers that go on either side of these screw mounts. As you can see, the tube which stores the retracted "rope gear" is clipped into the assembly with two nylon clips. Remove the motor and storage tube from the assembly taking care to to break the nylon clips. See picture 4.

Now go get a rag, because it gets messy from here. Use a flat-bladed screwdriver to pry open the nylon gear box cover. Hey! That picture is missing from my phone! Anyway, be careful not to break this cover as the gear will jam up without it snugly in place.

Next, remove the three screws holding the motor to the gear box. Set the motor aside. See picture 5.
