Thank you guys for all your opinions. I just solved the problem and here is the cause:
The master control switch on the driver's side affects all window switches. Even if all the other individual windows are working but the corresponding switch in the master is broke, the window will not function. All power and functions pass thru the master. I opened the master switch all the way to the motherboard. The top switch handle cover (the black color with the 4 switches, the side mirror switch, and the on/off window safety switch) can be separated from the underneath electronic motherboard which are attached with 3 small screws. Upon separation, I discovered that the 4 top handle switches have a "fork-like" or "claw-like' feature at their bottoms which move each window mechanism in a forward or backward manner so that when you push the switch handle down, the mechanism moves backward and the window goes down; by the same token, when you lift the switch handle, the mechanism moves forward and the window goes up. This "fork-like" or "claw-like" shape at the bottom of each handle catches and inserted into a small "knob-like" feature attached to the mechanism that slides it to move forward or backward. What happened to my passenger side window switch handle was that this "fork-like" feature broke and so could not control the mechanism. You cannot buy just the top handle cover separate from the electronic mechanism; you have to buy the complete unit which costs US$ 385 - 400 from the dealerchip. I was able to find a used one for US$ 75.00. What caused the handle switch fork to break, I do not know. My car is only 4 years old and 50,000 miles. I may have to write the Toyota company for an explanation or to suggest to research and develop a more sturdy design of the switches.
There you are folks. Lots of work and diagnosis but it saved me some money.
