The power windows work about 50% of the time.
Half the time they work, half the time they are stuck down or up.
I have replaced the control box in the drivers side door, no help.
Someone suggested it might be the PCM.

More likely the BCM (Body Control Module) If all 4 stop working,it could very well be the BCM shutting it down.Or it may even be the Master switch (drivers side). Find a shop with the proper scanner to watch what the BCM is doing and they can see if signal is getting out of the master switch to the BCM
