Ok guys today I experienced my first problem with aftermarket power windows I was rolling down my driver side window when i heard this bang so I rolled my window up and theres grease all over it. I just ignored it till I got back to work and asked my boss what it was (I work in a body shop). He told me its a tensioner and do not try to put it back on cause it'll cut my finger off. So my question is what would cause it to pop off
. He also told me to not use my windows till it gets put back on cause it'll burn my motor up. And I cant get it fixed till next week.
FYI: I dont know much about power windows.
