Door Windows don’t work. Best just to replace motor and regulator at same time?

What is your question?

First one door window just stopped working, then about a year or so later, the second door window simply stopped working as well. I can’t ever put them down, because they will not go back up again, which really sucks in the summer time, I tell you. I have a 2001 Chevy Cavalier Z24, very low mileage, 164,000. My brother has figured out that it isn’t the switch. From what I’ve read so far, it seems as though the regulator is attached to the motor when you buy them. I suppose to be on the safe side, I should just have both parts replaced in each door, if I went ahead and bought the parts, just in case both the motors and regulators in each of the doors now, might need replacing?

What makes this problem better or worse?

Summer makes things worse because it’s very hot in my car, a/c isn’t great & I can’t use my windows at all anymore.

How long has your 2001 Chevrolet Cavalier had this problem?

Approximately 2 years, maybe longer.
