1993 Nissan 240SX Q&A
1993 Nissan 240SX Question: Broken manual window assembly.
This is kind of rare, but it is probably a broken door window regulator. You'll probably have to get an entirely new assembly to install. - matte
It's not rare on 16 year old car. Bad regulator. You need to lubricate the window guides. The rubber is hard as a rock causing resistance on window. - backyard tech
