Wow- just checked the online price for this item and it looks to be $160-$240! That's insane! Time for some home fixit action.
Items needed: Stubby Phillips Head Screwdriver
Items nice to have: Medium Towel, Flashlight, Patient Helper
I actually did the repair first, so you will notice that the pics were taken after the fact.
1. Put down the rear third row seats. Gently pull the wall panel away from the body. It's kept in place with clips and takes a bit of pulling to get them to pop loose. I only pulled the upper half loose far enough to access the Shade Assembly.
2. Loosen the 4 Phillips screws holding shade to wall panel. This is where a stubby Phillips screwdriver is worth it's price as there is only a few inches of room.
CAUTION- here is where the towel comes in handy to lay under the screws as a safety net- if you drop one, it is gone into the abyss of the the body cavity. Also, a couple of layers of towel will cushion your forearm from the plastic edge of the wall panel.
3. With the Shade Assembly in hand, (recommend heading to the workbench with good lighting) remove the 4 Phillips screws holding the end caps together.
