One of the common problems I've had for a while, just never got around to. The plastic housing holding the wiper arm for the rear of my Golf snapped off in a bad winter. Probably from stress cracks and cold temperatures. Plus it didn't help when I sometimes tried to use the wiper when it hadn't fully de-thawed
Anyway, purchased a new wiper arm, blade and cap from Volkswagen (mine still had the nut on) and replaced it, job only took around 5 mins (10 if you count the mistake I made, which I will mention here)
Tools Required for Wiper replacement
13mm Spanner
Puller / Pryer / Screwdriver (optional) - but shouldn't be needed
Parts Required for Wiper Change
Wiper Blade Arm
Wiper Blade
Wiper Blade Cap
Procedure to replace wiper blade
Loosen 13mm nut still held on the rear wiper motor (assuming you still have it, if not replace)
Fit the wiper blade arm (make sure it's orientated pointing to the right - see below)
When I first fitted the wiper blade to my car, I assumed it swept in a left > right motion, this is incorrect. The wiper blade actually sweeps in a right > left motion. So instead of wiping my windows, the arm wiped my boot. Easy enough just reverse it
When you fit the wiper blade arm, align the arm with the lowest heated line on the window
Tighten the 13mm nut down on the wiper blade (torque values to be added) - nip it tight
Clip the wiper blade into the arm, there is a small hooked section. Slide the locking pin and let it clip in place
Replace the cap on the boot
All should be carried out and the wiper arm should be replaced with a working wiper
