[Mr._Graden]

I have a 95 chevy lumina minivan and the power windows aren't working. I checked the fuse in the glove box and the circuit breaker under the glove box and both are OK. I tried to find a replacement window switch to put in it to see if that fixed the problem and neither worked. Neither window works. Am I missing something else that might me causing the problem and where should I look? Would it even matter to buy a new power window switch? Is it possible for both motors to go out at the same time?

The best way to know for certain would be to remove the door panels to access the electrical harness directly at the window regulator motor.
If you connect a simple automotive light bulb across the window motor plug and work the proper window switch, you should see that light come on no matter which way you press the switch.
If you don't, you need to replace the switch (or find out if you have power and ground at the switch) and repeat this easy test. If the light does light when the switch is pressed both directions, you know the fault is the window motor. Otherwise, if the light only works in one switch position, you have an open power or ground wire somewhere (not too likely).

Yes, it is very possible that both motors failed simultaneously.
Test the circuit first.
