Power Window problem

1991 Cutlass Ciera S - The driver's door switches will not work. All 4 switches started acting up just now and then, but then all stopped working completely. The other 3 doors work just fine from their switches but not from the driver's door, and the driver's window does not work. I had this same problem a few years ago with a Buick but replacing the driver's switches did not solve the problem. I "played" with the wires yesterday to see if one was loose or broken in the door but nothing worked. Any ideas on this problem will be greatly appreciated! Thanks, Hayes

what did you find out
? I have got the same problem.
