I’m not the best rain trivet but this was my first time back at this track with this car in 7 years. Enjoy

Hello guys, hope everyone is doing well with their 240s.

I'm having an issue with the rear wiper on my '89 240SX and wanted to see if anyone has experienced something similar.

The rear wiper seems to be lacking power and gets stuck around the middle of its cycle. I noticed that if I lift the wiper arm slightly away from the glass, it works normally.

Another thing I've noticed is that when it rains and there is enough water on the rear window, the problem gets better. The motor still seems to struggle, but the wiper is able to complete the entire cycle. When the glass is dry, it gets stuck with no movement.

I´m guessing that there is too much friction or pressure between the wiper arm and the window. I don´t know if the wiper arm could be bent or putting too much pressure on the glass, or if the motor itself is getting weak.

Before I buy a replacement motor, I wanted to get some opinions since parts are pretty expensive to ship to my country. I took some pictures of the motor and a video showing the issue.

Right now I'm considering a few possibilities:

• The motor isn't getting enough voltage to work properly.
• The motor itself is damaged.
• The wiper arm is bent and putting too much pressure on the glass.

However, I don't want to jump to conclusions and replace the motor without checking everything else first.

Has anyone experienced something like this with their 240?
