sometimes the driver’s window will operate.

Either an intermittent switch or window motor issue more than likely.

You might try lubing the window seals and tracks. The car is 9 years old and rubber hardens with age, etc.
Not a lot of info has been provided so my comments are theory only; a.k.a. wild axx guess.
