3rd Gen Lexus GS Rear Electric Sunshade Repair

This is a part 4 video that documents how I went about repairing the rear electric sunshade that is only going up partial way. Lexus Part No. 64350-30050. The OEM replacement retails for ~$2000, but it's on sale for ~$1500. Still way too much. For non-critical feature in the car.

Here are part 1 through 3 videos that precede this:
   • 3rd Gen Lexus GS Lexus/Toyota Back se...   (Remove back seats)
   • 3rd Gen Lexus GS Rear Deck & Subwoofe...   (Remove rear deck)
   • 3rd Gen Lexus GS Rear Shade & 3rd Bra...   (Remove rear shade)

Though this work was done on a 2006 Lexus GS300, I believe similar issue and fix may be applicable to many other Lexus and Toyota models.
