honestly, I'm not too sure this is in the right topic but it didn't fit anything else.
Sometimes, when driving and I turn on my AC, my aveo shakes a little bit, not much but its definitely there. Only when I'm already driving though, if I turn my car on and the AC was still on, no issue. Just wondering if anyone knows about this or has experienced it before.
(I also remember one of my friends moms who owned a geo metro, when she turned her car on with the AC still on, it would shake very badly.) perhaps a GM problem? who knows?
