luckily the rear quarter window blinds are extremely easy to remove!

You will need a small pocket size flat blade screw driver, look toward the top of the blind on the right hand side there is a small notch, stick the screwdriver in the notch and pull back gentally, the blind should just pop off. To replace place bottom in first and snap into place. Just to let you know, for the most part, it is difficult to repair...mostly a replacement item, but good luck!
