Toyota Repair: Windows wont go down, toyota corolla, switch failure

Question
There is no power to all windows on my 1990 Toyota Corolla.

Checked the fuses, thier okay yet still no power to the windows.

The window motor was working but now it stopped working. What can be the problem?

Answer
Could be a master switch failure or a broken wire in the door harness in the door jam.
Check for power to the switch with a test light.
Wire diagrams available at www.techinfo.toyota.com.
You can use up to a 1993 diagram if 1990 is not available.
