To change the rear wiper blade on a VW Golf Mk5 (2004 – 2008) doesn’t require special qualification, you can do it yourself. For that you have to follow just 3 simple steps:
STEP 1: lift the rear wiper blade up
STEP 2: you pull out the small part of the wiper
STEP 3: put the wiper blade perpendicularly to the wiper’s arm and pull it out
To put it back, you have to fix it perpendicularly to the wiper’s arm and then and place it in the normal position. Pull back the small part of the wiper blade and put it back on the rear window.
