The passenger and 2 back power windows will only work when using the driver's controls. The lights are on in the individual switches. Some kind of relay in the driver's door?

 

Thre's a "Lock" switch at the driver's door that locks out the other switches to keep the kids from fooling around with the windows. I'm assuming you are familiar with the proper operation of that switch. It could have gone bad and need replacing.

 

Thanks. I've played around with the switch but still the same problem.

 

Then the most likely source of the problem is that lock switch. It's an integral part of the whole switch there, not a separate component. There is no relay in the circuit after that switch.
