Relays. The switch you push energizes a relay which energizes the motor. The relays are interchangeable so switch them around and you may find the bad one(s). The task is to find where they are clustered.

You may have a bad fuse in the fusebox of the vehicle. Your pattern fits the pattern of the fuses. One fuse protects the driver's window and the right rear, another the passenger side window and the left rear. I had a fuse with an invisibly small crack once and I took it to the dealer and as soon as the mechanic saw that my passenger front and rear left were out he told me to check the fuse and that is what it turned out to be.

Those switches do go out from time to time though. They aren't terribly expensive and are readily available from on-line parts places.

Prices on switches vary from $11 - $22 here:

I would start out with fuse first... take them out and put a new one in. They look okay in place but when you take them out... you will see they are bad.

If that didn't work, then I would take the switch apart and clean all the contacts inside it. It is almost always the switch when you can open but not close... or vice versa.
