aight, for the person with the regal...
when you press a button, any of them you here the motor run but nothing moves RIGHT?
well, look under your seat, theres a PLASTIC (cheap GM) connector that connects the motor to a mechanism.
More than likely, it shattered like mine did. Even if you epoxy it, and everything itll still break because that plastic piece is just shit.
Do what i did and cut a length of steel pipe, and squeeze in both ends to where it can be used as the replacement connector.
Youll just have to look at it, eye it, measure it, and do it yourself
