Electrical?

Just take one system and troubleshoot it. Did you check for voltage anywhere? Fixing one system may or may not fix the others. If all systems have a common cause, then fixing one could fix everything. As an example, If all those systems work off ignition voltage, then I would check voltage to and from ignition switch. Give me a second to find wiring for power windows.

In the diagram, see the circuit breaker, voltage to the circuit breaker goes hot with the key on. Use a testlite and check for voltage at the circuit breaker with key on. If no voltage have to check feed to and from ignition switch.

Sometimes the wiring going into the driver door will break, because the driver door is opened and closed so much. Check wiring.
