- Aerodynamic improvement.
- It's an old, ugly wiper and very much an eye sore.
- I've never used it once, it's so useless. The minute you get up to speed the water clears off the back window anyways.
- Weight reduction; the motor assembly weighs about 15 pounds.
- The Nismo N1 race cars have no rear wiper for all these reasons.
Remove the 3 screws inside the trunk that hold a black plastic cover over the rear wiper motor assembly. Then, unplug the 2 wire connectors and remove the plastic cap covering the wiper arm assembly on the outside. Remove the nut that's holding down the wiper arm. Oddly enough you have to unscrew the wiper arm by twirling it around, and it comes off in 5 revolutions.
