about window opening control

Hello friends, the glass opening buttons on the sofor side are sticking, I'm hurting, getting caught, hurting, do I need to change, do I need to clean it, or would it be useful to clean it, good night

Hello, when I first bought my car, we cleaned it, but it did not work again, it was not working again, it was not working, it was closing, it was painful, it was not closing or it didn't hurt, it was 70 TL.

the same problem exists in me, I need to change it, it keeps 70 TL.
