How do you fix a Honda 1993 civic power windows when they all stop working at once?

There are a few reasons why all the power windows in a 1993 Honda Civic may stop working at once. Here are some possible causes and solutions:

3. Faulty power window switch: Check the power window switch for any damage or signs of wear. If the switch is damaged, replace it.

4. Faulty power window relay: Check the power window relay for any damage or signs of wear. If the relay is damaged, replace it.
